Bandwagon
Bandwagon is a new iTunes backup service (for Mac users) that backs up your iTunes library to Amazon S3 or to CDs/DVDs. The CD/DVD part is meh to me, but the online backup part - which can be automated/scheduled - sounds very interesting...
(Disclosure: by posting their logo and linkback to their site by Feb. 22nd, bloggers get 1 year of Bandwagon service for free.)
[UPDATE: I do not recommend using this, at all. I won't even have it for free. See here and here.]
