Approximately a year ago I asked a friend of mine to knock together a proof
of concept of a similar idea I had back then. Cost me a bottle of Port, but
was well worth it to me (yes folks, JF pays up for work done, even if the
currency is more liquid than most)

See Dirk's example here:

There are some keyboard issues, but it's on GitHub so if anyone wants to
take a stab at cleaning it up, have at it.

Yes.
