I completely understand your point and from our offlist discussions I have
been very supportive of getting some of these ideas like the a common H.460
framework base and H.239 into Opal.

It would be good to have these kind of H.460 features like NAT and also the
myriad of other H.460 extensions like text messaging (h460.tm), follow me,
click to call, presence (h460.presence in development with PacPhone and
GnuGk) which are available in h323plus into Opal.

I very much look forward to that close working relationship into the future.

The fact that all those features aren't ported to Opal (yet) is not
lack of interest but mainly lack of time. I think Craig and others
pointed this out as well. I myself am very interested to have a full-
featured H.323 stack in Opal, and I am willing to do some of the
porting work myself, but right now I am struggling to find even time
to work on my main project, XMeeting.
I have to admit I never really worked with the OpenH323 stack, but as
much as I can tell, Opal not only offers multiple protocol stacks but
also a better software architecture design. This itself should make
it a reason to port the applications above to Opal. However, as long
as most H.323-related work is done in OpenH323/H323Plus, the two
projects continue to diverge, making it harder to switch to Opal
later on.
I think that the developers of Opal / OpenH323 should put more
pressure on the projects mentioned above to migrate to Opal. I know
it is hard to convince someone to fund such porting work, as there is
no direct financial benefit for the funder, but at some point the
cost of maintaining "backwards" compatibility by far exceeds the
benefits of having this backwards compatibility. One should not only
focus the projects one is interested in, but also consider the
OpenH323 community  and what's best for that community as a whole.

However,  I will by no means criticize your project split-off, as I
can fully understand your motivation for doing this.
