I thought it would be fun to instrument the ZODB so that it uses 
something like syslog to send out a short message for every oid loaded, 
and give the connection that loaded it.

This data (oids and when they are loaded, per connection) could be 
gathered and analysed, and pre-fetching strategies could be tried out 
against the data to see how effective they are.

I wonder if some of the bayesian / pattern-recognition techniques 
developed for detecting spam might help?

The same kind of set-up could be used to analyse a connection in real 
time, in a separate process, and send messages to the process to load 
object that it is predicted might be required soon.
