[kepler-dev] Can I use Ptolemy actors in Kepler?

Everyone seems to want *all* actors to be fully searchable and fully 
documented in the tree, but no one wants a startup time >.0001 seconds. 
  You can't really have it both ways.  Either you have more 
functionality in the tree or you have less startup time.  I know there 
are ways that we can optimize the current system to make it a bit 
faster, but IMHO, it's not going to startup as fast as wordpad anytime soon.

right now, most of the ptII actors are in the tree.  If there are ones 
you want in there that aren't, it's easy to add them.  catch me on irc 
or write me an email if you want a tutorial.  You can also create your 
own ontology for your own customized views of the tree for you or your 
project.  That is a bit more complicated, but there are several examples 
of how to do it and I'm sure shawn would be willing to field any questions.

Another thing I'd like to mention is that anyone is free to dig into the 
startup time problem and hack on it.  Dan has sent out several good 
emails on the subject in the last couple weeks.
