These comments may be old and outdated ;-)

It is more or less totally irrelevant which obs-worker package is
installed, because all it does is

 curl http://api:$port/give_me_the_workercode | tar xf

and then executes the downloaded code. So the only thing important is,
which build version is on the OBS server :-)

Never had that at work, but my workers are relatively big machines
(144GB RAM, running the workers on tmpfs), and in my "research
installation" at home, I just do small testbuilds to check if it works.

That's not really necessary, if kernel-obs-build is used then the host
kernel is not really that interesting to the build VMs anymore.

I have not yet updated to 2.8, but the update from 2.6 to 2.7 was pretty
painless in my environments.
