Mercurial has two top-level packages, 'mercurial' and 'hgext'.  Works
just fine.  I know for sure that distutils doesn't care.  Neither does
Python, nor RPM nor dpkg nor any other software that you're likely to
encounter.

But why not just keep everything under 'buildbot', and make sure that
everything needed exclusively on the slave is in 'buildbot.slave'?
Maybe create 'buildbot.common' for shared code that has to be on both
master and slave.  There's really no requirement for multiple
top-level packages.
