If you've got more than a few servers, you pro'ly wish you had configuration management software. In fact, by maintaining that handful of kickstart configs for new hosts and the veritable slag-heap of shell scripts that you run on already-deployed servers, you've pretty much built your own.
But other folks have already invented this wheel:
bcfg2 (interesting...)
Lets you define what a configuration "should" look like and then have agents tell you what's actually out there; if they'd just document it, humans could use it!
cfengine (safe choice)
That for loop you're using to update your systems is getting pretty big and your shell scripts are all pretty kludgey; cfengine gives you the ultimate automated for loop ... but it's ugly!
puppet (my choice)
By now you're wondering if you can just write your own system where communication over https allows clients to run scripts periodically. So did these folks! (And it rocks.)
