Yes, you could create a "function table" and keep a list of all the 
functions that need to be called. You can then alter the behavior of one 
method at runtime with out having to pass a function as a parameter. Of 
course, global variables are tricky things, especially whe you're 
threaded. It's probably simplest to just pass the function pointer as a 
parameter to Shuffle(). If Shuffle() indeed has multiple entry points, 
and they all fight to have their version of PlaySound() run at the end 
of Shuffle(), then you may run into problems.
