1. why reduce the network traffic? does the network traffic itself slow 
down things that much, or is it really something else?

2. how do you pass a Tcl_Obj across the network? you could also hold a 
cache of the last commands in a Tcl dictionary, so that the Tcl_Objs are 
preserved client-side.

3. how often are lines exactly duplicated? if you don't have much 
duplication, you can't save much by removing the duplication.

I think that the answer is to simply use proc, and not worry about 
bytecode, as proc takes care of it better than what you can do otherwise.
