Actually, I've been thinking about this some more and realized that it
would suffice if I could just do the connect part as in

       [simulator object] connect [UDP object #1] [UDP object #2]

dynamically within C++.

Problem that arises with this issue, however, is: how'd I get the object
numbers in the compiled hierarchy? I suppose I need to work with node IDs
or similar but I haven't manage to figure out the details. Basically, all
I need is an address such that I can send my custom AppData objects to
another application. There's nsaddr_t but I don't know how to derive that
from the node name. (which is all I've got from OTcl and is the same as
this->name_, e.g. _o12.)
