While there may be some workarounds to make this possible (as others
have already pointed out), I think what would really help here is
support for load balancing as suggested here:

https://sourceforge.net/tracker/index.php?func=detail&aid=1524611&group_id=73177&atid=537004

I initially suggested this in a mail back in April
(http://sourceforge.net/mailarchive/forum.php?thread_id=10215131&forum_id=32301)

Unfortunately, neither got any attention from buildbot's developer(s)
so far.

Needless to say, a solution that could be merged back into buildbot
would be most beneficial for other buildbot users.
