Good, that answers my speculation.. If I or someone else wants this
functionality on modern DGD versions, reimplementing the network package or
adapting the old version is basicly the only way, and since the development
version is pretty much a moving target, keeping that uptodate can be a fair
amount of work.

And that underlying code would need changes to support a network package of
sorts, and I smell an old discussion about networking functionality in DGD :P

I suppose the connection code could provide an interface for setting up
outgoing tcp connections besides accepting incomming ones, and similar for
udp. The communications code would need an interface to call that.. but hrm,
then you are basicly reimplementing part of the network package, and still
don't have something that could be used by the extension interface if I
understand you correctly. Still, having an interface for doing those things
would make life a lot easier...
