Much applause!  You're about the first team that's "gone public".
Good stuff, keep it up.

Actually, not all that many changes; and it's not really felt to be
particularly preliminary.  It's quite implementable as it stands.
Simple versions were used to verify the 94.9.32 document (actual
title:  "Universal Networked Objects") before it was submitted.

Since there's so much interest in IIOP and UNO (Arctic being one
example!) I'd like to reemphasize the point about not yet complying
with CORBA 2.0 in terms of the bits put on the wire.  I was kind
of hoping it'd talk to the stuff I've been working on, but it's not
ready for that quite yet!


Have a good holiday, all!
