You might want to look at Apache Guacamole. It's a web application that acts as a VNC/RDP/SSH client (that is, a web browser connects to Guacamole, and Guacamole makes a separate connection to a VNC/RDP/SSH server and renders the result in the browser). There are instructions in the manual for configuring audio with VNC and RDP. I think the tricker part would be sending the appropriate Xinerama notifications or whatever is required to tell the X server "A second monitor has been plugged in", but perhaps someone better acquainted with VNC or RDP can say if that's easily done. > > Cheers, > > --Barak A.
