Keeping hosts updated

Rather than run all apps/services on a single host, I make extensive use 
of multiple VM & baremetal systems (local & remote) for my setups; most 
of them are Ubuntu, with a few Debian & BSD's in the mix.

One of my pet peeves is keeping them updated.
At he moment I manage to do that with a script that uses cert-based 
SSH-connections to remotely run the update/upgrade/dist-upgrade process, 
but this is not exactly ideal (for a number of reasons that I'd prefer 
not to get into at this stage).

Does anyone have a better way of doing this?
