Yes, both ethernet and Wifi

Sure, it allows you to install Linux without any trouble. Gentoo,
Fedora and Ubuntu are known to run fine. It's a powerpc with 2
execution threads, that's why it's easy.

Problem is to use its SPUs, AFAIR they're exported to userspace as a
filesystem where you have dirs mapping to SPU and internally the
mailbox, register, ... so requires another offloading logic.

Given IBM's size and interest on cell being widely used, I do think
that they can ship one or more PS3 to each interested developer, given
that it's a well known and committed developer. If you or any other
core hacker is interested, just let them know.
