Because of the fact that I work for IONA, it's inevitable that Orbix issues
will be raised in CORBA discussions that I'm involved in. I wish that
weren't true, of course, but I know there are issues and, trust me, I'm
busting my ass over here to fix them. I wonder, though, whether we should
turn this conversation on this mailing list into a "I hate ORB XYZ
because..." tempest -- frankly, I'm not sure a lot of people here are
interested in such details, and those that are can simply jump over to
comp.object.corba. (But then again, I'm not the moderator, and I could be
wrong, so maybe I should just be quiet. :-) )

The term "Internet" in this context is mostly marketing hype.

There is the new Firewall stuff in the OMG which was largely driven by
Wonderwall, but I do not know the details. (After all, there's only 29
hours in the day (when employing "Doug Schmidt time distortion," of course)).

There are some strong movements being made towards the implementation of a
CORBA branding program that will ensure specification compliance among all
the supposed "CORBA compliant" ORB products. Products that do not comply do
not get the brand, pure and simple. I believe this will help.

We are too, believe me.
