MythTV already has various speeds of ff/rw.  I think the big limitation 
is most remotes don't have analog levers, just buttons, so you speed up 
with multiple ff/rw presses.

However, you can do pretty much exactly what you want with a Wiimote.  I 
haven't used this in a couple of years, but I did have it working and 
the "trigger and twist" method for ff/rw worked well.  The further you 
twist the faster it goes.
