This is pretty much how I imagined it would go, but expect that we  
keep the door open for portions in Java, and keep that in mind from  
the outset.  I'm also open to others that wish to work in Java from  
the start.

I do want to make sure that we work things out so we *can*  
interoperate, so parts of the later phases above can come earlier,  
just because there are parallel efforts that due to approach to the  
problem, do things sooner.
