Define multiple trees ? Different branches of the same project ?
Multiple interdependent projects ?

FWIW, http://build.fluendo.com:8080 is a buildbot for HEAD of GStreamer
projects, and :8081 for the stable 0.8 branch.  So we do both, unless
you were thinking of something else as well.

Sounds sensible.  Warren also had the idea once of being able to combine
status info from several masters somehow.

In my case, I made TaggedBuildFactories that only mark changes important
if they match the tag they are factories for, and I've made these
factories ignore projects it doesn't care about.

Ie, with B depending on A, A only builds for changes to A, while B
builds for both changes to A (because a change in A could break the
build for B) and changes to B.
