i wrote a patch some time ago that implemented a framework for doing this. 
actually, its primary purpose was to address the eventual lack of bit space 
in the unit flags field. it wasn't accepted because a) it was "too OO" - IIRC 
and b) because i never wrote any code that actually used it. it was just 
supposed to coexist.

it can be used to exactly what you're talking about. it changes the bit field 
describing unit capabilities into an array. each byte in the array describes 
some segment of capabilities/properties (like settler properties or diplomat 
properties). each element of the array is a bit field describing the various 
capabilities in the segment.

i also wrote code to load to the bit fields from the rulesets and xmit over 
the network so there shouldn't be too much work there.

it could probably be used to solve this issue too, although somebody from the 
AC team would have to look at it.
