I read through the same thread, I think it was 95 percent War between two
individuals and 5 percent peace between the other members....

If I had an HH80, of course, I would take it apart and see how it works. (I
love taking things apart, by the way my screw drivers and cutting knife
would work just as well on other manufacturers samples, heh,heh)

Even if a pedal has a reostat style sensor for sensing continuous input
levels, it would still fall back on the module. How many positions can it
translate into? The other question in my mind is, are there five distinct
sounds in the module for the hihat or is just two (open/closed) that are
being extrapolated with an algorithim. 

If there are five levels of sounds in the module for the high hihat, then
having a variable pedal, would have no benefit. The pedal would output say
0-128, but the module would have to bracket the levels and assign them to
one of the five sounds:

output of 0 = open
output of 1-32 = closed 25%
output of 33-64 = closed 50%
output of 65-96 = 75% closed
output of 97-128 = 100% closed

The real question then is what can the module interpet, five input levels or
128 input levels (or more)?  It seemed that the Roland pedal could output
the 128 levels (I think) to the computer based software that Chris was
using. 

I said it in vdrums and I say it again here. If you can make a optical
tracking mouse (which senses motion across a surface) that can translate an
inch of movement across a mouse pad into 1024 position on a computer screen,
and sell that mouse for under $30, then a hihat pedal based on that type of
sensing technology could be cheaply incorporated into a hihat pedal. Can you
imagine 1024 positions sensing on the pedal translating into 1024 of sounds
between open and close or 800 sounds from open to close and 224 sounds
between close and closed real tight? 

I really think that the module manufacturers are going to have take a
lession from the computer industry. Where as computers have graphic cards
with dedicated high speed processors and memory for doing nothing but video,
I think they need to either have a "add-on" processor card or a built-in
dedicate processor for handling nothing but the hihat/pedal input. Then and
only then will it approach the accoutics version in quality of sound and
expression.
