It's probably just like the available free software out there that does the same stuff.

You put a program on your PC, that programs shares whatever you want, such as all your music, videos, etc; and then you can access your files with a username and password from anywhere with internet.

Streaming videos tends to suck if they're high quality, but music usually works fine, as well as pics or text. I tried www.orb.com and that worked fairly well...we used it on my Wii at a friend's house to look at some pics from my PC.

I use Orb from time to time. It is free and streams from PC to Wii via wifi. It is too slow to work for videos or tv but does a decent job for music and works well for pictures. Maybe if my PC and Wii were actually connected it would work better.

Orb likely works better for the Xbox 360 because the 360 is a lot stronger.
