I'll return to the Zune posts in ~2 weeks with some info on the ROM files, and changes between versions. Eventually, I hope to have a profile of every chunk of code on that system available for reference. I'm also working on a little thing for my car, may put details of that up, to.
Some random thoughts before then:
Zune-linux.com died again - very strange, and now the zune hack scene appears even more dead than before.
This crackdown on console mod chips is revolting. The car analogy is appropriate here: this is akin to raiding the garage that installs aftermarket parts in your car.
