the way to do this is via a callback function:
with sys_vgui you call a function in the pd-gui process, which then can 
send back a message to a pd; you have to bind your object to a special 
receiver to receive this message.

you will also be able to receive this message via a [r <special 
receiver>] object, there is no way to do an exclusive communication.
