Hi Timo,
Yes it´s related, but I don´t understand '... You'll just need to implement a filesystem that allows distributing a single user's mails to multiple servers ...'.
My idea is just in the direction that we don´t need to care about filesystem, we don´t need any distribuited filesystem...let it be as user wants....at any some proxy level, the end storage can be ext3, reiser, S.O linux, freebsd, and so on. I think that the more elements we insert, the more complex and hard to mount/debug the solution would be.
I mean Dovecot accesses filesystem through a simple abstraction layer. You wouldn't have to implement a real OS level filesystem, but you'd implement a "proxying Dovecot-filesystem backend" that sits on top of real filesystems. It's probably not much of a difference to what you're thinking about, except in my mind it's entirely isolated from actual Dovecot code. There's just a simple API that the backend needs to implement and it'll work with Dovecot.
BTW. Maybe http://www.xtreemfs.org/ or http://www.gluster.org/ already does what you're thinking about? I haven't looked at them closely enough..
