Interestingly we at egnite plan something similar. Our first idea was to
implement ZigBee, but license issues makes this far less attractive.

Adam's license fits well and we can probably steal a lot from his code
to extend the Nut/OS stack.

A little bit tricky, but not too difficult. At least routing is already
prepared for more interfaces.

I'm only unsure about the release. We have 4.9 beta available for some
time now. Actually I'd prefer to have 4.10 (or 5.0?) out first, before
starting to add such a modification like IPv6. There is still some
clean-up work to be done (mainly the docs) for the next stable version.
I'd also like to have the qt based configurator and stable AVR32 builds
as well.

Any other opinions?
