Skylaunch sell a telemetry system called 'Launch Assistant' which relays
the actual airspeed of the glider to an LCD display mounted somewhere in
the view of the driver. It costs a few hundred dollars in total. See:

At Feshiebridge, Scotland, AIUI they developed telemetry for
indicating glider airspeed to the winch driver, and it was said to
work very well. IIRC, it did not send an airspeed number in knots, but
rather an indication of too slow, a bit slow, OK, a bit fast, or too
fast (or something like that) which is what the winch driver really
needs to know, they believed. The unit in the glider was calibrated
for the glider type.
It needs somebody with first hand experience of it to tell more, and I
don=92t know if it has been kept going.
