The big problem is what the protocol should be. Use some existing RPC protocol? It should be something extensible so that a plugin in imap process can talk to a plugin in storage process, without the base processes knowing anything about the details (e.g. imap-quota plugin asking quota usage from storage's quota plugin). In any case the client side API should be asynchronous. That can make it annoyingly difficult to use though. Wonder if I could switch to erlang or something for the imap/pop3 processes :)
