A nice tutorial from the CNET Applesource, on how to stream video from a Mac to PS3.
It reads like an uber-geek lovefest - a page full of code and software directives. But this could actually be one killer how-to.
Reason being that MS and Sony both really want to push IPTV on their various video game stations, especially MS. A key part of this is user-generated-content (UGC) which basically means people jamming custom game cutscenes into their own little entertainments, sharing them, and so on.
If you can then mix that all up with real video footage and other media applications - you have a powerful group of forces at work.
And as few desktops both have and deserve a reputation as an ultimate media mixer as the Mac, we could be looking at the beginnings of something much much bigger in time.
