Microsoft has released LiveStation in for private testing. It's similar to Joost in that they use p2p technology to deliver a full screen TV experience; however, they claim they're not competitors. As the name implies, Microsoft is looking to focus on live TV whereas Joost is an on-demand service. However, it is certainly not hard to imagine each being extended to do the opposite.

How much longer until we see campuses getting rid of satellite TV services, either for the campus or just the language centers? I don't have a test account for LiveStation yet, so I couldn't measure the bandwidth. Joost was a rather heavy user at 600kbs, but as compression technology continues to improve (and with bandwidth becoming cheaper), it may not be long.
