OnChip and SiFive, two groups aiming to develop and release RISC-V platforms, have announced they will collaborate. From OnChip's crowdfunding campaign:
Ever since SiFive's HiFive1 campaign was launched just a week after we launched Open-V back in November, we've both been getting a lot of questions about how we might collaborate. It's taken a while, as these things do, but we finally have a concrete answer we think will benefit everyone, not least the RISC-V community. Here's how we're collaborating:
...
Open-V Will Use the SiFive E31 CPU Coreplex
...
All Open-V Peripherals Will Be Compatible with SiFive Chips
...
SiFive Will Donate Wafer Space in a May 2017 Tapeout
...
OnChip Will Contribute to the Free Chips Project
Sounds like good news for those hoping for RISC-V and open hardware designs to become tangible objects.
Note that the SiFive HiFive1 campaign was successful and has already shipped to some backers while the OnChip OPEN-V campaign looks like it will not reach its goal.

I used microchip's programmer adapter to program the SOT23 chips:

I just looked at the datasheets, and as far as ICSP is concerned, the 10F220/222 have the same pinout as the 10F320/322. I too chose this chip because it was so tiny and inexpensive. Amazing to see what something so small can be used for.
I'm also really fond of the 12F1571/1572.
