I don't want to sound like a fanboy, but I can't immediately think of a feature that i'd want that the PS3 doesn't already have, except for a video playlist option and a broader codec/upscaler support but I'm sure that's do-able by either Linux distro or firmware. I've got a launch model so a lot of data storage cards are already supported...
Perhaps a DVD/BR burner? or draft-n wireless support? we are talking theoretical here after all!
