But eh...wasn't the player going to support 100base/T ethernet also?

I started laughing when I read that, then I realized there was a chance you might not be joking about it.

In case you aren't joking:

100baseT ethernet isn't something you can update with a software change. In order to do 100baseT ethernet, it would need some special hardware on the player's motherboard. Among the things needed would be a 100baseT ethernet chip set, and a PCI data bus to support that chip set. The car player has neither.

If you were joking, then my reply is as follows:

"They had to leave that one out along with the Cure For World Hunger feature."
