Yeah, we fully intend to support the CVS HEAD for PTII in our kepler 
builds, as it seems like the only way to really keep synchronized.  Over 
the last week several of us have been building against the CVS head, 
with mixed results.  Sometimes it works, sometimes not...haven't yet 
figured out the differences among these builds yet that cause the 
failures.  We'll get the issues worked out fully and then post 
instructions on the web site.  It should be as simple as checking out 
the two trees, set 2 env vars, then run 'ant ptolemy run'.  I think the 
problems we are hitting are due to us not encoding in our ant build some 
of the dependencies that you cover in your makefiles.

In addition, we need a way to try to incorporate Kepler changes into the 
PTII tree.  We are working on a variety of changes relating to data 
access and semantic typing, and several of these require UI changes in 
vergil.  We have been developing them using the ptolemy extension 
mechanism through the configuration, so they could be used or not 
depending on how the configuration is set up.  But there are many areas 
of vergil which are not configurable, and so we are extending those 
areas to be configurable where needed.  Ultimately, we need to 
contribute this code to PTII through the code review process -- I think 
the easiest way to do this is to have a couple of Kepler developers who 
have write access to the PTII CVS tree and can contribute code after 
consultation with PTII developers (like Christopher and yourself).

In many ways I would prefer to not have to maintain two separate CVS 
trees at all, but I currently don't see a good way to do this because we 
want the Kepler project to be fully open to a variety of contributors, 
while the PTII tree is really reserved for the Berkeley Ptolemy project. 
  But it would be nice to use just a single integrated tree.  I would be 
interested in chatting with you about whether you could see the two 
projects really sharing a cvs tree or not, given the project management 
implications this would have.
