> Juniper has already ported it's JUNOS to run on x86.

huh :) i was/am under the impression that with junos, juniper started with freebsd as the core, and then added lot's of stuff to it, specifically in control-plane and a bunch of kernel extensions as well.

if that is true, they were already x86 compatible...

with cisco things are very different. i don't think ios ever ran on a bare-metal x86. this is not for the lack of trying though (if you know folks who have worked on ios, check with them, writing about it here, doesn't seem right)
