Hi,

embedding a plugin is pretty generic. But that doesn't help you. Plugger is
a generic way to embed application output from your local machine into a
webpage for data the webpage delivered. (Like using your favorite media
player to display embedded video) XEmbed uses messaging between apps, but
again, all on the same machine.
HTTP is designed as a one-way protocol, data comes from the server to your
machine. To get your keystrokes back to the server, you need to use
different means. Why don't you use ssh + x11-forwarding? Or
nomachine.comnxserver? Or VNC? Except for x11, they're (mostly)
platform-independent and
all can be tunneld over port 80, if needed.

For your idea you would need two-way realtime data flow. Unless you're eager
to do some heavy apache-mod coding (i doubt even that would help), i don't
see any viable way to do this.

The only way this might work is, when you use mplayer to embed a x11 display
and somehow pass the keystrokes etc to the app running on that display. I
don't think this would work for anything than localhost (I did something
similar with an embedded mplayer displaying v4l inputs, works on localhost
only).

I don't know if your requirements forbid ssh, if not, i'd always go that
way.

Peter Marquardt
