I have
ORB on my desktop (on 24/7) and connect while I am away either thru ORB or UltraVNC.
I can stream all my music, grab any files I need, have a look at my webcam to see who is in my office

and more.
Haven't tried the TV thing (yet) as I need to run an antenna cable to the DTV card to get a signal. I will report further when I do that.
Sure beats a shoe phone
