I've written some primitives for ParcPlace ST-80 version 2.3 that let
you send and receive simple objects (nil, Boolean, SmallInteger, Float,
String, Array of anything in this list) between Macintoshes.  I've also
built a proxy object system on top of it - giving you remote procedure
calls in effect (remote message sends).  This uses a custom protocol,
not MacTCP so maybe it isn't useful to you.  I've posted the source on
BIX in the Smalltalk area. 

By the way, remote message sends are almost trivial to add to Smalltalk. 
Particuarly in PP version 2.3 which has these nice oop numbers and lets
you disinherit a class by making its superclass nil (doesNotUnderstand:
is the hook where you add in the remote message sends).
