A remote control can be implemented: Bino has a "controller" class that
can send commands to the central dispatch (and is notified of events,
but that is not required here).

You can implement a simple UDP controller that receives the "play"
command and sends it to the dispatch. Have a look at lirc.cpp for an
example.

If possible, start with the current Bino sources from git, because we
recently had a major restructuring which cleaned up the controller/
dispatch code.

An alternative might be to use Bino+Equalizer for synchronized video
output over multiple processes/graphics cards. That depends on your
setup and requirements (I did not understand what you mean with
"alt+tab").

If you need help, just ask on this list.
