My point is that the "push a button" technique is already handled by the
Gitian build. (Even though it's more like "make 20 sandwiches.") I just
want to caution you against redoing a lot of work that has already been
done. Did you know that the Gitian build has a Vagrant configuration?
https://gitweb.torproject.org/builders/tor-browser-bundle.git/tree/HEAD:/vagrant
Many of these battles have already been fought.

Also understand my motives: in the future, I don't want the building of
PT bundles to fall post-hoc to pluggable transport authors. I want them
to be made as a side effect of the vanilla bundle builds, so that nor I
nor others not interested in making bundles will have to make them. So
while improvements to the bundle.git system are welcome, I eventually
want to get rid of it completely.

Pushing a git repo somewhere is a good way to share your changes.

Virtualizing OS X is problematic. There are many OS X testers, however,
on the tor-qa list, to which new bundles are announced before they are
published.
