My startup is working on that. Sign-up at http://degoo.com and we'll let you know when we have a beta ready. /Shameless plug.

I can e-mail you my Master's Thesis, which covers some of the theory behind it (although, it's in Swedish).

Might be worth writing a 2-5 pager in english summarizing some security features.. I'd sign up if I read something that made me feel safe putting my data on it.

Thanks for the input! Yeah, information about the security-features are very important. Right now we are focusing on actually making it secure. Once we have a client ready we will most probably improve the information.
