Wow, Mike.  I would have never figured that one out. 

If I changed the Track.pm to use the same method for defining the 
subroutine to use as the Payment.pm uses to call the payment modules, 
that seems like a simpler way for future users to plug in a custom 
tracking module.  Then they would just have to pass the name of the 
module to use.

Would that work better?
