Brian Krebs writes on how browsers choose to display IDN. The issue here is of course spoofing valid URLs with visually similar letters. You probably would notice the lame attempt in the department line but some of the international characters are very similar or indeed identical. Depending on your personal preferences it might be a good idea to use punycode instead. Could save you a headache later.

    Well, the biggest problem with inventing your own internet is getting other people build and to use it. I think I'll finish my work on a time machine first. ;-)

    the biggest problem with inventing your own internet is getting other people build and to use it.

    Use it, sure; adoption would be a problem until a critical mass was reached.

    But build it? Most devices capable of operating on an internetwork have the hardware (ethernet, wifi, etc.) and software (networking stack that can perform tcp/ip) built right in or easily available.

    Instead of connecting your devices to the Internet, connect them instead to your internet. The infrastructure (the links between nodes, not the routing, dns, etc.) is going to be largely the same; besides leased lines between locations, you could even tunnel links across another network (such as the Internet).

    I would hope that a person starting his or her own internetwork would start with something like ipv6 (and not, not, not ipv4) but I expect the opposite.
