Orb.com
Orb is one of the coolest free programs I think I have seen in a long time. Many people might know of Slingbox, well, this blows that out of the water, from what I can see so far. Orb allows you to access your files from your computer from anywhere. They have different interfaces, and you can even access and stream music from your mobile phone! Furthermore, you can even share your files, including your television channels! I believe more people should check this program out, as many times I access home computer documents and music, even recorded TV, from work or my mobile phone using the easy web interface. All you have to do is install the server on your computer, and then access orb from the net to get to your files! F-R-E-E!!
Music, photo, video, TV, files!
