Just speculating on remote connections securely, using open source resources,
over an Internet connection. I think port forwarding would work, but for
that, you need a fixed port, so I am wondering about whether or not there is
a way to do it without having to fix up and recompile CPRSChart every time a
new one is released.
Do you remember the post I passed on from Joel Ivey
around Dec 21 that made it sound as if that port issue was going to be
addressed?

None of our work, as far as I am concerned is confidential. We release all
of our source code and appreciate any feedback as well.
The solution that we chose was to use a UCX-type listener on the server (on
VAX and I believe GT.M) that does not require a callback and is similar to
the type of connection made with telnet. This and the use of different
initial headers ( {XWB} vs [XWB] (new style) vs <XWB> (M2M broker) ) also
provides the ability to differentiate between the old style connection and
the new style so that some new parameter types could be added for data
transfer (e.g., a global list in addition to a list). On NT, I believe the
connection as it is made spawns off a new listener, so that it does not have
to do a callback as well.

Well, I thought maybe this addressed it. The trouble is, I did not entirely
understand Joel's answer to my question and I do not understand exactly what
this patch does either.
If we could securely connect using port forwarding to a server and have lots
of people work on configuring VistA and then checking out the results with
CPRS and all, it might improve our ability to move along Open Source
development efforts.
