Wow, excellent.  How far along are you?  Any way I can help?

I'm thinking something along the lines of the CLR's CodeDOM model.  It's
an abstract code generation model with things like
CodeConditionStatement that represents an "if" statement,
CodeMethodInvocationExpression to call a method, etc.  We'd have to
write it from scratch in Java without using any CLR code, of course.
When we had the interfaces done we'd write the concrete implementations
of the Java, C++, C#, etc. generators.  Then the code generator would
call our CodeDOM interfaces and all generators would benefit from any
improvements to the code calling the CodeDOM.  It's clearly a lot of
work and might require cleaning up the runtime interfaces as well.

Eric.
