NASA has a problem with #1 and #2 in space. What to do? Crowdsource it, in the form of a contest where anyone can submit a superior method. The contest just ended with NASA awarding $30,000 to the winning entries.
NASA astronauts' current method of waste disposal involves using a diaper during spacewalks and launch and entry, but these systems can be used only for about a day. The agency noted that it is difficult to design pooping systems for microgravity, where fluids and other things float. Maintaining good hygiene for these systems was among the primary challenges participants were tasked with solving.
In a description of the challenge, NASA said it was looking for technologies that have a "technical readiness level of 4" on its "ready for flight" scale, meaning that the solution could be tested in one year and be ready for space in three years. NASA added that it would consider solutions that would need more time if they were considered breakthroughs.
The goal is to use the system on a mission in the next three or four years, the challenge page said.

Heh, there has been a LOT of thought on that.
Just to add, from a sci-fi book I can't remember the title of, aliens created a toilet when asked by the humans. Looked like a regular toilet, but was perfectly frictionless. The author spent quite a bit of time describing the magic of poop sliding, without leaving any stains, down and out a drain.
The most interesting one, that I think is a real winner, came from Garden of Rama by Arthur C. Clarke. In some sentient arthropods decided to help with the #2 needs by developing a symbiotic life form to live *inside* your intestines. It lived off excrement and released only gas. So instead of needing to take any shits at all, you had some creatures living in your butt that took care of it for you. Butt butlers, if you will.

What you want is a cylindrical room with a toilet pan on the wall which can be spun so that the astronaut can sit and get the jobby done. It doesn't need to spin that fast, since you only need a little centripetal acceleration to make Mr Hanky go in the right direction.

Keeping airtight seals when spinning just one room is hard. Easier to spin the entire object in space. However the ISS (for example) is not designed to be spun for artificial gravity, neither is anything else right now. Besides, the are plenty of times when you are not in a position to be spun around so you can poop (e.g. space walks).

Me neither, but NASA highlighted spacewalks as an issue, so presumably if the spacewalks are long, you need to be able to poop in your suit. A quick search took me to this page: http://www.answers.com/Q/Which_astronaut_have_longest_space_walk [answers.com]
Where apparently the longest spacewalk is 8hrs and 56min. I can feasibly believe an astronaut may need the loo during those almost 9 hours in the suit. Quite a few spacewalks are multi-hour long themselves.
> Why would the seals need to be air tight? I was thinking it would be inside the main hull of the space craft, like a giant washing machine cylinder.
Because then you would have splatter everywhere, and floating turds in space isn't my idea of fun really. Unlike in a gravity environment, things don't drop where they are deposited, but rather float around and find their way out of small holes and cause issues.
While inside the cylinder may be spinning within the hull, the hull itself isn't, so between the hull and spinning cylinder you would have floating turds and piss. If not sealed that will get out and float around the rest of the station, which sounds like a recipe for problems, not to mention the smell.
Plus I don't want to be the one who has to go clean the hull where the cylinder is. Easier if the system disposes of the excrement into bags, which can be jettisoned when convenient.

If I read TFA correctly the issue really is what happens when there is a catastrophic failure in the spacestation and the astronauts need to put on spacesuits for an extended period of time. Those diapers are going to get pretty ripe after 4-5 days.

While I'd prefer artificial gravity in most of the space station, you don't actually need to spin the entire room.
You can grab a bucket and swing it round and round in a room and the room can be airtight, there's no problem with airtight seals.
So have the toilet in an air-tight room, astronaut goes into the toilet and then the toilet spins. Stuff ends up in a container in the toilet. Dispose of waste when toilet is no longer spinning.
Anyway NASA is a sad joke of an agency nowadays. They should be building stations with artificial gravity, not trying to do reruns/"franchise reboots" with fancier tech.

With centrifugal acceleration, there always a Coriolis one. At small radii, it will have values comparable with the centrifugal force, resulting in bending Mr Hanky.
The end of mr hanky closer to the emitting orifice will have a smaller velocity than the distal end, which needs to be accelerated to stay along the same radius. Not a problem at large distances from the rotation centre - otherwise you'd see it whenever you poop on Earth - but at a rotation radius of 1 meters, 15-20cm - the "drop" of a constipated mr hanky - will be non-neglijible.
Now, 1m rotation radius implies a 2m diameter. Place other components required for toilet rotation and containment around and the size of the toilet will become far from trivial in the economy of space aboard the space station.

Diapers and outside catheters seem to be the current options.
For females, an inside cath seems a likely solution for #1.
For the backside, the body does pretty good containment, until it can't.
Perhaps some sort of internal flushing system, working with the natural containment system.
Probably would take some getting use to, but I bet the folks with the right stuff could work it out.
