yup. The trick I'm looking at is that many of those different styles 
come down to "syntax sugar". If I have a

   protected void setXXX( blah )

I can call that from the subclass, using a constructor, service(), or 
just make it public, but it comes down to the same thing :D

yep.

I took a look and played a little with just about all of them. I found 
one which does compile time bytecode modification reasonably well; it 
seems like that's the best bet (none of my basic objections apply), 
unfortunately none of the project I see existing in a year from now 
support it atm. What's more, that doesn't mesh well with radical 
IDE-supported refactoring (something I forgot how to do without 8-)). I 
don't want to end up doing my own mock implementation; there's too many 
already.

yep. It looks like its Just Not Possible to do the things I want the way 
I want without writing most of the tools and features I want myself. 
Several people have told me now :D. I'll just have to do the typing.
