[LV2] worker thread question

[hermann meyer]

Hi
New to the list, so first hello to all.

I come here with a question about the worker thread extension, it's:
How could I ensure that the worker request will also be send from 
internal host UI's ?
Say, I have a GUI element that send a message to the engine control 
port, to fire up a work sequence, how could I let the host known that 
this special UI controller do that, and that his internal UI must do the 
same to ensure all work like suspected?
Even, if the URI in use is a self defined one?

regards
hermann
