The problem is not only one of protocol, but one of structure.  How DO works is
based on two things:

1) How it encodes the objects sent as parameters.  This is tied to the
archiving   of GNUstep vs. that of MOSX.  They're fundamentally different for a
number of reasons.
 
2) How it encodes the signature of the selector in GNUstep vs. that of MOSX.

While #2 might not be difficult to fix, #1 is very difficult to fix because it
could effect how ALL objects are encoded in base and gui.

Sounds cool.
