Thats a neat idea.

Couple of questions:

* How does this thing work, as in how can I invoke a binary from a browser?
Is there a webserver involved, which would launch the application when a
particular url is accessed?

* How do you access the HTML canvas in your QPA plugin? Is it something
like how flash renders inside a browser. i.e the browser gives the flash
plugin it's window handle, and an area to draw, and then the plugin renders
it's contents there?

* Is there a browser (NSAPI) plugin needed for it to work?

* Do you have some rough docs/drafts which explain how it works?

I'm not a GUI guys, so not sure if I can contribute. Though if there are
some non-GUI aspects to it, I could pitch in.
