Bulk updating dozens of (not identical) servers

I agree with the others on the boon of config management systems. I use puppet to manage the configuration of around 30 Linux servers.

For once-off commands (checking the version of all running kernels, etc), I use the Fedora Unified Network Controller (func). It's written in Python, so if that's your forte, a few moments with python-apt to write a new func module may be all you need. I'm going to get around to it some day, but maybe someone already has?
