I suppose if there is a bit of brokering taking place in each of the "layers"
of Piper (e.g., Grandparent is part of DL), then it would not be possible to
completely replace all brokering components (if we use the GPL).

Give me an example of a "plugin" for Piper.  Will a plugin work via CORBA?

One license for all of Piper?  I agree with that.

I think it will depend on whether plugins use CORBA or not.  If they all do,
then we don't really need the LGPL.  We can use the GPL.
