I'm interested in peer-to-peer networking technologies.
Om is almost a distributed operating system. It is designed to be a part of a decentralized social network, with simple but powerful functions.
So, around you, there are people using Om just like you, some of your coworkers, your brother, and your best friend. You give them your IP address, which is nothing but a sort of computer phone number. Then your computer is connected to theirs.
By right-clicking on a file, you can send this file to people you're connected to. Of course, you can send private mails, you can chat...
When you're in one of your Rooms, you can invite people to join you in this Room. Your computer will automatically broadcast the screen to every computer connected, using Icecast built-in technology. (Behind the curtain, the broadcast is pyramidal : each computer broadcast to 2 other computers, it's a cascade). The mouse cursor of each participant (an avatar with an arrow) can be seen by everybody, and everybody can interact simultaneously with applications used in this Room. Optionally, voice can be transmitted.
So you can surf the web together, work on a 3D animation together, develop a software together, play games, whatever. You can teach and learn. You can share.
