They claim to be real-time, and with kernel hooks into reads/writes,  
it seems promising to run on top of the OS..

Maybe I should voice my assumption that a Maildir mailbox would only  
be accessed from one server at a time, not both, and Dovecot indexes  
would be local and not replicated.   And I suppose I'm assuming small  
files - which is probably the biggest hole in this active/active theory.
