That is a funny coincidence, indeed :-)

What I've been doing so far is setiing the hook in a local clone and  
perform pulls in a cron job. Indeed, these hooks react in the same way  
if new changesets are added by a pull command. Since I've been doing  
that for big collections of repositories, I call that "mirroring".

I had to do that even for software I actually maintain, just because I  
wanted to setup private buildbots for several customer projects that  
depend on that software and I felt that adding hooks for all of them  
in the public reference repos was wrong (did not think at that time  
that the hooks can't push changes to several buildmasters anyway).

Since I'm also a recent user, I can't say if that's considered  
standard or best practive, but I'm a bit tired of it. In particular,  
it makes experimental setups long to create.

Anyway, there's some progress, see http://trac.buildbot.net/ticket/ 
2307. If you want to give it a try, feedback would be really useful,  
but it's definitely not ready for production.

Cheers,
