Ideally, all pl's should use the same protocol. It should be language
agnostic and allow different regions of the code to origin from
different languages. That way, it would be possible to single step a
plpgsql function that in turn calls a function in pljava. Incidentally,
the JDWP (Java Debug Wire Protocol) was designed to do just that. But I
think it would be very complicated to cross language boundaries even if
we did use that.
The JDWP and the architecture that surrounds it might be a good source
for inspiration though. See:
http://java.sun.com/j2se/1.5.0/docs/guide/jpda/architecture.html.
I have no idea if this would fit .. but just to throw something into the
mix that was designed to be somewhat language agnostic (with a slant
towards web scripting languages):

If it seems like it could fit I can create contact with the two authors
Derick and Shane to discuss this further.
