[Spambayes] Sharing database among multiple IMAP clients?

Firstly, I agree with Jesse that it's really not worth sharing the  
databases - just train each one separately and you should have good  
results.

Note that we don't recommend doing any initial training.  We  
recommend only training on any mistakes and unsures.

If you do want to do this, then a good choice would be to use ZEO,  
for which there is already a (relatively untested) storage system  
written for SpamBayes.  There're also mySQL and postgreSQL options.

Depends how big the USB drive is <wink>.  This should work fine.

Storing the database remotely in some other way (e.g. ZEO) would be a  
more sensible method, IMO.
