Is anyone familiar with MOF 2.5 shipping rate modifications? I'm using Russell's UPS Rates and Quotes lookup from Jan. 2007 which gets me custom UPS rates based on weight, zipcode, etc.

I'd know like to add some additional shipping options to those returned by the UPS API and maybe override some of the returned rates when I have free or discounted shipping offers. I've gone through some of the code but haven't had any luck. Has anyone done anything like this to their installation?
