Perhaps I'm missing something but if I want to identical copies of the router,
but with different configuration data, to be running at the same time
I don't think this solutions suffices.

I just read the click-combine man page and it does not indicate that this 
is what I would get from the combination.  Correct me if I'm wrong but 
it seems that that tool combines multiple, independent, but related
routers through link elements and what I want is the following:

So that there are four interfaces, 2 assigned to each click router, and
the two routers do NOT share any information.  I know there are ramifications
for parts of Click that interact with the OS (such as the routing table)
but those I know about.  If each could be it's own thread that would
be great too.

Makes sense?

Later,
George
