Experience on a mob by mob basis
 

I was wondering if it is possible to set the amount of experience a mob gives to something other than the EXP_FORMULA define. For example, a boss is typically harder than a trash mob of the same level and I would like to make the boss give more experience than the trash mob.

You could certainly write your own custom code to do it, but not in the stock code. Another possibility is doing something in perl with EVENT_DEATH and granting quest exp.

Like this but a global version that gives exp based off some calculations using level or mana regeneration (since mobs don't use mana regeneration). The possibilities are grand, but writing it is another thing.

You can do it the cheesy way with a dropped quest reward item.
