the only problem I had (and it was severe enough to push me back to UW) was that 
client side filtering seemed to trigger reindexing every time a message was 
moved.  This problem made my e-mail processing very very slow.  If I had moved 
to maildir, I think things would have been a very different story.

I will say however that I am quite confident that Timo will solve this problem 
and also make it trivially easy for people to convert away from mbox to maildir 
  in an opportunistic fashion as they access each mailbox.  And I am sitting 
here with mboxes just waiting to be a guinea pig!

It will be also interesting to see the solution for mail delivery when you have 
a mixture of users accepting mail through /var/spool/mail/XXX and others in home 
directory maildir.  And yes, I know of sites where they need to do this.
