i don't know how you use it, but:

"plugin-dispatch" has a very clear scope: it is a way to interact with a 
GUI-plugin from your patch.
it is decidedly *not* a way to interact with the Tcl/Tk interpreter 
(that happens to host the GUI plugin).

the workflow is:
- the GUI loads a plugin
- the plugin registers a new method (along with a name) with the 
dispatcher, using the ::pd_connect::register_plugin_dispatch_receiver proc
- from the Pd-patch you can now call the registered method (by the name 
it used to register the method)

the plugin is of course free to do whatever it likes to do with the 
received data, so it could provide a low-level interface to the Tcl/Tk 
interpreter.

i hope this clears things up.
