you may have read it already, but anyway there is a new (open source) software: Cleversafe (The company won this years Technology Innovation Award. The software enables you to save data via different (I don't know if it's possible to choose them) servers in encrypted packets. Every server gets only parts hence every connection can be used. A redundancy protocoll ensures restoring date if a server should be down.
I would like to know if anyone is going to use it.
All the best,
