distributed objects question

[la le]

hi, i was wondering how good the performence of the
distributed objects were, specifically, I'm trying to
make a game, and was making the server parts for
keeping track of where every object is, what its
doing, etc.

that part will then allow multiple users to connect,
and it will broadcast changes to all the others, but
since it keeps all the info on objects in a
NSMutableSet, i was wondering if the users should
address the server using id_tags's (numbers of type
int), or just have them talk as if the server were in
the main program, and pass the object id's themselves
(the ones of type id).  so does gnustep's distributed
objects already do that (or something similar behind
my back) or will it be better just to deal with
id_tags on all objects?
