Mark,
I hope you or someone else is able to come up with a Thunderbolt controller
for the many of us who have or will be receiving Thunderbolts. A controller
based on a LCD touchscreen would be great in the since that one could
assemble a self-contained frequency standard based on the Thunderbolt.
Keep us informed in you progress with this project.
