All that is true. However, Arne may be able to get something like this 
to work. It seems there are three components to a py2app application bundle:

One is the "magic of creating an application bundle", which includes a 
specific binary, etc.

The second is the all the included packages, and modules, including the 
Frameworks, shared libs, etc that are needed.

The third is the actual application user code.

If one where to build an application bundle that included all the 
packages for a given app, you could then swap out the application code. 
This wouldn't be a general purpose solution, but could be a way to 
distribute a particular app, doing the final building on another system.

Come to think of it, it would be nice to have a "just replace the app 
code" option to py2app -- it does take a long time to do the complete 
rebuild.
