Actually, I was thinking more about a *server* limit rather than mailbox 
format imposed limits; and that this limit would be for administrative 
reasons rather than technical reasons.

IMAP already has a built in limit of 2^32 - 1.  On many systems, a file 
can't be larger than 2^31 - 1.  Cyrus imposes a limit of around 100MB, and 
I'm thinking about a similar limit in UW imapd.
