I can't think of anything too problematic, actually, aside from 
actually agreeing to do it.  One would have to come up with a way to 
"mangle" ObjC class/protocol names so that they contain namespace 
qualifications and do not collide with names constructed by hand.  
(E.g., mangling 'org.gnustep.MyClass' as 'org_gnustep_MyClass' would 
not do, although you're probably right that leaving it as 
'org.gnustep.MyClass' might just do the trick.)

If you did, I can't see it.  :-(  My first inclination was to rely on 
C++ namespace notation, but that would mean that only ObjC++ users 
could benefit from the features.  Your notation could work with both 
ObjC and ObjC++, and seems quite reasonable.
