Yes, but we aren't there yet ;-)

I didn't know about that page. Interesting - but I don't think I'll go
for HTTP-based backup/restore.

Right now we have the registration process, and that pushes an SSH pub
key from the XO to the XS, and creates a system account on the XS, I
want to

 - move that "user acct creation" to a chroot or vserver
 - use it to backup/restore over ssh
 - initially, use rsync over ssh for the backup (and define a simple
scheme to walk the stored data)
 - longer term, move to a git-like protocol on the wire
 - at some point, have a git-like storage mechanism on the server
side, with a sliding window over time

the above merits a more fleshed out description but I'm dealing with
lousy connectivity atm - so apologies for now...

cheers,
