Is there a way of knowing how many clients are using one's virtual endpoint?
It would be very handy to know if/when someone starts using the port, so as
to start generating (for virtual inputs) or reading (for virtual outputs)
data on those ports.
Extrapolating from this, the MIDI server could open a MIDI driver only when
someone requests an enpoint to it. At the moment the server opens the drivers
when it starts (and so powers the USB devices at that point) and thats
already *really* cool, but it would be even better if the devices where
powered up only when someone opens and endpoint to it. I'm thinking power
consumption on laptops, etc.
