Merging one client-side junk email filter with another, learning from each other

Question

I have my desktop email client which is teaching a filter about junk emails, and I am also using the same filter in another machine.

I want then to take the learnings of both filters and merge them into a big one.

A server based filter might do the work, but I am looking for a client-side solution.

How do I get one spam filter to merge with another so both can know about each other's rules to processing junk mail?

Spambayes will let you copy its database to other machines and according to this forum post you can merge databases with a provided script.
