The basic idea I have currently is that a file/partition is connected to /dev/loop0 on a remote server, which I have an ssh connection to. I hold the key (for cryptsetup via dm_crypt) on the local client. I'd like to mirror the loop device of the server on the client. Once that is done, I would run cryptsetup with the key on the client and mount as normal. The end application would be for remote secure backup (rsync?) of a second encrypted volume on the client.
