ahhhhhh, i gotcha.
so your going from a touchpad to the client.
I was going from touchpad to server.
Sorry buddy, this one is out of my league
if it's even possible, since the touchpads are communicating thru the web browser that is hosted on the server, so there would have
to be some way the server knows which client your trying to send the communication too. kind of a 'port forwarding' scenario.
this sounds like it would be a great plugin. where you can send 2 variables, the client name, and the command. then the plugin would take that command and send it up to the proper client.
just a thought.
