Intel and Nokia announce open source telephony project (oFono)

I donno. StrongArm is probably the most convient platform for them to do development with. If it's actually Intel putting work into it then they probably have toolchains and development machines setup for other purposes already. Just pull them out of storage and there you go.

Otherwise I expect that they are coded to be portable and all that, seeing how Intel is more and more interested in x86 on handhelds and whatnot.
