As it turns out, it appears that you were correct when you stated that 
mixing static and dynamic libs is a bad idea. I had no idea. After 
running several different tests, I was able to get it to work.

I put the serialization code inside the same dll that the serialization 
operation was initiated from and that worked. I then put the 
serialization code inside of a different dll and initiated the 
serialization from a separate dll. This also worked. I also tested using 
the manual void_register call and implementing a dummy serialize method 
in the base class, both worked when I took the static lib out of the 
equation.

Thanks a ton!
