    Thanks for looking at the release and the comments!

    Why do you think we are using version 3.0 of Ptolemy II? (If we are, 
then I made a major mistake!) The build was (supposedly) made using the 
head of the PTII CVS as of 10AM on 9 July. All the PTII code is the 
kepler.jar file. If you click on the 'Ptolemy Introduction' link in the 
intro.htm screen, we are linking to a screen that says "Ptolemy II 
Version 5.1-devel".
    Maybe we mislead you by not exposing all the latest models and 
directors in the 'Workflow Component' tree on the left? It was decided 
to only exposed four directors (CT, SDF, PN, and DE) so as to minimize 
confusion for non-CS Kepler users. I think the code for most of the 
actors in PTII 5.1 is included so most Ptolemy demos should work (if the 
user has Java3D installed; I didn't include it in the distribution).

    The first demo failure may have been due to you not being connect to 
the Internet when running? [I never checked that case and it seems to 
run OK on any machines that are connected.]

    I'll look into the other comments that you made and see if I can fix 
things. Thanks again.
