Whoops, it got chopped off... Here we go again.

While I think that this would be great for a inter-process or 
inter-network communication mechanism, I don't think it's a very good 
idea for inter-thread communication.

Serializing/deserializing is usually very inefficient and is also 
extremely hard to do in a C++ environment. You'd need to know how to 
marshal each and every class in the objects type as well as containment 
hiearchy. Leaving all this to the implementor of the top-level class 
will definitely break the basic OO principles, and will be bound to be 
very error-prone.
