This sounds really, really cool! I am thinking of the possibilities of
separating storage to frontend. That way one could build dynamically
distributing mailboxes. Use local ressources of many storage boxes
instead of using FC storages all the way. Or just "replicate" mails
twice to have them redundantly stored (hadn't you the idea of a
replication part, anyway?).

Maybe one could "lend" some parts of erlang based database
http://couchdb.apache.org/ ... :)
