For most files I store on ubuntu one, file sharing and web access are irrelevant.

I would like that directories could be marked as encrypted and have the contents of those directories encrypted on the client. Those directories could not be shared of course.

The key exchange to the registered hosts should ideally be done via something akin to a PGP-encrypted channel that ensures that the keys are never decrypted in the Ubuntu One infrastructure. In fact I might be better to use the infrastructure to merely establish a connection between key-ring applications that then negotiate exchanging private keys generated for these directories via a channel that is itself encrypted (either via PGP and existing keys or TLS).

For the web access I could only imagine browser plugins that allow client side de/encryption via the key ring management.
