Ok.

ah, good to know :)

Ok, then I'll write that guide and publish it. When it's done we can
meet on IRC. Will try to get it done this week or the next one latest.

If we have shell access we dont really _need_ post-commit auto update,
as we can install buildbot in the buidbot user account. That's how I've
done it in our current deployment.

What would the procedure be if we need to do more things than just
software installation? for example, change Apache settings, maybe create
some directories, etc... should we contact you in this case?

Yes, right... in that case there will be some heavy work installing
packages :)
