its both simpler and more complex than you think. the easiest method
would just involve adding some code directly to ardour, handling the
same internal signal that the GUI does to indicate recording status.

a better way would be to have Ardour emit a few bytes (OSC, even) to a
pipe or socket, and have another app listening.
