So basically, what you are telling me is to forward on a link, node directly 
on a node!?

Actually I tried this. But when I (in C++) do a TclObject::lookup(oif) I get 
a null pointer back - it can't find the link :-(

The OTcl reference name I'm doing the lookup on should be ok. I tried doing:

[$link info class]

on it in Otcl, which responded with "SimpleLink".

Does anyone have an idea of why TclObject::lookup() does not find the object 
for my link?
