I'm not sure what you're trying to accomplish here, but to create a new 
application object, I'd just do:

class MyNewApp(grok.Application):
   ...

somewhere in some module.

I don't see a reason to copy ftesting.zcml, testing.py, and so on. I 
also don't see a need to copy setup.py and such. What you seem to be 
describing is a way to organize *two* Python packages (each with an 
application) together. I'm trying to understand why.

I'd make this a completely separate package, with its own setup.py and 
so on, perhaps maintained during development in the same buildout. So:

project/setup.py
project/src/myproject/

and then:

project/anotherproject/setup.py
project/anotherproject/src/anotherproject.py

and list 'anotherproject' in the 'develop' list of my buildout.cfg so 
that its setup.py can be picked up.

I think you could construct 'anotherproject' with grokproject as well 
should you so desire. Of course it's not containing application code 
it'd be nice to be able to construct it with another paster script, one 
that constructs a Python package (with at least a configure.zcml that 
uses the grok command). This is where I'd see paster come in.
