Thanks for all the great tips y'all!  I will definitely look into
deadwood--hadn't heard of it and it's got such a catchy name.

On the 7k, it's one of those things where they were like "yeah...you're
gonna want to take care of that at some point."  I was hoping to upgrade
first and then remove some of the code either through core functionality or
improved contribs--views 2 for example :).  Expect another dev mailing list
request in a couple of months on how to refactor monster modules.

I don't think there was much/any core hacking, but there was some
contributed module hacking "somewhere".

Seriously though, it's working software made by really nice, really busy
people.  They recognize the limitations of the current state and want to
take the time to migrate and create more maintainable software now.  I've
slung far smellier code before (I've got a BA in English), and besides, this
way I get to perfect my svn diff skills.

Thanks again y'all,
