It'll be here someday indeed.... not today
I have to agree with V and say working with PC controlled Audio and Video while it is comming the processing demands for a real time 3D enviroment would be unreal!
I am not a huge Linux fan but the way some of the OS versions are designed It will probably be most likely to happen there first!
Video rendering tests I have done
*XP-sp2 64 bit single core AMD processor....90min video encoded to mpeg4 from avi. took 2hrs and 15min ..new $1200
(56 processes running)
*Vista 64 bit core2 Quad Intell processor.....90min video encoded to mpeg4 from avi. took 45min................new $2500
(62 processes running)
*Linux KDE Dual core AMD processor...........90min video encoded to mpeg4 from avi. took 27min................new $800
(9 processes running)
This is due mainly to the fact that mostservices in windows run all the time where as Linux is more of an on demand kinda system
Anyway untill we can do it for real these might help give you a good feel!
