Re: [Overflow] Re: DL and PL integration

First, for Jarl, I would suggest that you subscribe to the Overflow mailing list
by going to 
http://lists.sourceforge.net/mailman/listinfo/freespeech-overflow
It's fairly low-trafic, since there's only Brad and me so far!

I think there are other ways to achieve Overflow 'language bindings'. Note that
using CORBA for BL-PL communication doesn't help in that respect. What's
important is that Overflow C++ nodes can communicate with nodes written in other
languages. I think that the best way to achieve that is to write a special node
for every language we want to support. That node would just be an empty node
that would call the 'foreign' node, either with a function call, as a process,
with CORBA, ... that is left to the one implementing the language binding. As
the the PL itself, it could still be linked in the BL. I really see the BL as an
executable that runs on each machine and that links with the Overflow libraries
to do the local processing.

So far, monday and tuesday are fine with me.
