There is no way to communicate (at least not through the default master
config) between masters that I know of. You can however, use interlocks
to kick off sequential slaves, so depending on how you think about it
you could set off multiple projects with the same source tree.

Is this a coincidence or did you read my post?! :-) (i.e. source keys

I think you've pointed out an option that I missed, master build steps.
Looking at buildbot.process.step there is a Dummy step:
"""I am a dummy no-op step, which runs entirely on the master, and
waits 5 seconds before finishing with SUCCESS
this could be modified to allow build steps (e.g. just calling a
function in the master.cfg) to allow source filtering etc. If this step
had access to the change list (and perhaps other features) it could
determine how the build proceeded. This might be useful for your project
dependency checking. A problem might be that the build factory has to
create build in order for this step to run (only to be aborted if we
decided that the filtered changes, or dependencies are not ones you
