    Well, I think it is even simpler than that right now. All you 
should need to do is present a list of the "types" of nodes available 
(which you can get from the DL through the CORBA interface). Then the 
user will choose a type, and the DL makes it for 'em. 
    URIs and remote nodes and all of that stuff are for the future, 
and the location of remote nodes should probably be semi-transparent 
to the user interface, since the DL will end up handling most of that.
    So, for at least right now all you need is xxx = node name, and we 
can forget aobut the yyy :-).

This is not really true since there are no XML tags. The DL talks with 
the user interface exclusively through CORBA now, so there is no need 
to be giving the user interface XML, when it can just give it 
functions to call. Have you had a chance to look at the "How to Write 
a UI for Piper" thingy? Are you opposed to what I'm doing with the 
UIL/DL interface?

Yeah, this is the right way, even tho it means more work for me :-).

That's all the way I'm thinking about it. Congrats on managing to get 
up to speed so fast, it took me forever to figure out what was going
