store

backend storage

but encryption at rest: are the data stored on-disk in encrypted format?

in github.com/oleiade/trousseau they might be, yes.

camlistore : our eventual target; especially for user's keys. User's set of keys should easily fit in memory, so performance/space should not be a problem. There are iphone and android applications for camlistore already, and camlistore will have an SMTP interface, so we should be able to get sane replication/backup strategy in place for users

Backups and perforance for the server side: we may need to be fast to support websites with lots of traffic; start with straight (memory mapped) boltdb for now.

camlistore notes:

git clone https://camlistore.googlesource.com/camlistore
cd into that dir
make
camlistored # generate certs

there are already fuse, iphone, android clients. yes!
