@bascule would full homomorphic encryption allow off-site incremental backups of encrypted data if you have encrypted diffs?
@typed you don't need homomorphic encryption for that. You can already do offsite incremental backups to a P2P grid with @tahoelafs

@bascule whoa. I was only aware of Duplicity-style incrementals where entire directories are replaced. I'll check that out -
@typed Tahoe works kind of like Git. You can think of the backups as immutable persistent trees -
@bascule looks very promising. I was convinced you'd need to have hom. enc. to allow secure updates without manual intervention. :) Crypto!

@bascule@tahoelafs just finished trying it out and reading docs etc. I like the idea, but no public-key auth or file metadata tracking :( -
@typed@tahoelafs public key auth is an inherent part of Tahoe's capability system (for mutable files). Not sure what you want exactly? -
@bascule@tahoelafs oh, hm, I just realised you could ensure the web server is on 127.0.0.1 to keep all node IDs secret?
