There isn't an IPC on the Mac yet, but here is a quick and dirty approach
(I never tried it, but I don't think it shouldn't work):
Use the system resource file, which is common for all the application, as a
place to leave messages. Define a resource type which will hold the messages.
Each app will check this resource type in its main event loop. If it  finds
any, it will check it, decide whether it belongs to itself and if it does
remove it & handle it.
To post a message, AddResource of the known type to the  system file.
The resource should be something like:
msg = record
  from : Str255; { the name of the sender }
  to : Str255; { the name of the recipient}
  message: Str255;
end;
I hope this helps.
