I thought about writing something that would grab something like loose-screw's recent module list and use that to update a set of *NetLoadModule lines. It would probably require NetLoadModule be changed to use a split name/version instead of the current combined method, but that's no big deal.

There would be a problem whenever a module changed how it worked in some fundamental way, like where the newer vers of mzscript don't load scripts from step.rc by default. You need to be able to tell people "here's what's changed" and allow them to choose whether or not to update. (haven't seen sharpe's system)
