I apologize, I just see now that I wrote non-sense :^P
What I meant is that aqua.c will be put inside  "main" and not under 
the unix/ stuff. Specifically to aqua.c: I want to put in there all the 
api to access directly the Cocoa bundle. What we have implemented now 
(Simon) is to let the aqua module call the bundle, i.e. a module 
loading another module.

As for the modules in general: the latest plan we have discussed (but 
not decided yet) is to make all the GUI not modules but packages. This 
allows for more flexibility (for example, you add and api to the 
package not into R itself and you don't need to rebuilt everything, 
just the package)

I think this and many other stuff are going to be discussed at useR by 
the available r-cores.

I'll put a tarball of the RCocoaBundle, just leave me few hours as I 
have other priorities these days...
