IMHO erl_interface provides great support for building a
single-threaded C node. If you want it to be multithreaded, then
you're on your own (i.e. just as much as with any C application).
I never tried to do a double connect like you do. It is sufficient to
connect from one side and then you can send messages both ways.
Another possible issue might be that C nodes are primarily meant to
talk to Erlang nodes, not between themselves. So I'm not sure how well
a network of C nodes will function together. Maybe someone who tried
it can tell.
Checking out gtkNode seems a very good idea, especially if it covers
much of what your own gui nodes need to do.
