AllMyData:  Interesting peer-to-peer storage "grid" in which copies of each users's data are encrypted and scattered among many peers for backup.  Service is free if you agree to house 10 GB for every 1 GB you back up.  If you pay a modest fee, you may store data without providing corresponding storage yourself.  It makes sense for many broadband users with excess bandwidth and much empty disk space.  It will be interesting to see if they can make the business model work.
