Andrew -

I don't recall that vic ever worked with hardware encoding on the
parallax board - i think it just used the raw capture interface. Vic did
work with the DEC board, I forget the name of it, because Steve and
Lance made it work.  I think it could be made to work and it might take
a couple of weeks for each side - i.e., encoding and decoding.  

I don't know that it makes sense to have this work with vic, but it
would be very useful to have it work with the rvic and/or rvc programs
we use for webcasting.
