Buildbot has a scheduler called "Nightly", which would perfectly fit here. You 
can schedule those full builds on e.g.: 23:00

Not quite sure - need to check that. But there is buttoon "force build" on the 
web interface to retrigger a build, even if there was no "event" (e.g. 
commit). But this would also call the Build-Profile without the "make clean". 
But we could create a "cleanup" Build-Profile, which is using the same build 
directory. And do this "force build" for this "cleanup" Build-Profile.

But very likely there is such a feature and i just didn't found it yet ....

With every commit, or nightly/once-per-day?

Yes, thats planned.

Sure, i already discussed that with my manager. I guess some of my colleagues 
will also support me on maintaing this environment ...

It's planned to setup the buildmaster in a VM. So if there is any HW failure 
or I run out of time, i would just handover the VM to someone else. The VM is  
dedicated to the buildmaster ...

I thought also about running a Git repository for the used buildmaster 
configuration. Since the master configuration contains all the build profiles.

Ok - cool. As soon the VM is up and running i'll contact you regarding remote 
access.

Daniel
