Yes, that does make it more clear. Thank you.

There are quite a few times I have wished that Gambas had an embeddable, basic web server. As far as I know, gb.httpd can be 
used only in the IDE. It is based on thttpd [1] and, I assume, heavily customized for that purpose.

Websockets are very useful for remote control applications as they behave more peer-to-peer than client-server. But, alas, we 
don't yet have a websocket server either.

All I can suggest is that you code up a crude HTTP server on top of SocketServer. You can parse the request from the client. And 
then, based on the URL and/or Query String in the request, take appropriate action in the desktop app and emit HTTP/HTML 
responses back to the client indicating current state of control. For examples of HTTP requests and responses see:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Session

I don't have time at the moment to code up a simple example, but maybe this is enough to get you started.
