[kepler-dev] [kepler-users] Recipe for using Ptolemy JAI actors?

[David Welker]

Wouldn't it make most sense for us, as the Kepler project, to make a  
JAI module in Kepler? After all, it seems unreasonable to me to have  
everyday developer/users have to do so much hacking with how we use  
Ptolemy in the build to get this to work. Also, such hacking will not  
be easily shared. It seems to me that JAI is important enough to  
enough scientists as to be worth making into a module that can easily  
shared.

More generally, I would argue that as we get requests like this (for  
functionality in Ptolemy but not normally accessible in Kepler) that  
we make new modules. What are we going to do when we get the next JAI  
request? Tell them to go through all these steps again? We could give  
them much simpler instructions: just use the new JAI module.

Does anyone have any thoughts? Is this a good use case for a new module?
