That's pretty much what I do, but I first do a function_exists() on  
the function I actually need from that file.  If it doesn't exist  
*then* I require_once().  (I'm told that require_once is "expensive"  
in PHP.)

I don't claim it's the best system (yet... ;-)  ) but you might take a  
look at Strider Core: <http://code.google.com/p/strider-core/> --  
perhaps it will give you some ideas.
