Barry,

I don't think that Maildir or a database backend solution (such as 
Exchange) suffers from this same limitation.

I would be more interested in knowing how sensitive this would be to 
latency if using an IMAP server that isn't on the same device as the 
Asterisk server (or perhaps even a remote IMAP server)?
