[binc] Scalability issues....

[Forrest Aldrich]

When scaling to a system that supports potentially 100's of thousands of 
users (and irregardless of which MTA), how to deal with the issue of 
users performing IMAP indexing and searches?   If your mailstore is NFS 
mounted, even over GigE, there are some serious demands on the network, 
mailstore, etc.   How to remedy this scenario?
