I would like to have a number of different smoothing algorithms so that
you can easily try different ones. Currently [hid_smooth] uses
maxlib's [average], set to do a weighted average of the last 10 events.
I'll have to come up with more specific names so that I can have a
number of different smoothing objects available.

Unfortunately, it looks like Wacom didn't write a HID Manager driver,
so you have to program using the Wacom API in order to use the tablet
data. If they had made it part of the HID Manager, then [hid] would
work for tablets on MacOS X. The Linux input event system is unified,
so basically everything already works with [hid] on GNU/Linux. There
is a project to write free Wacom drivers for MacOS X
(http://tabletmagic.sourceforge.net/ ), but I don't know much about it
yet. I don't even own a tablet...

Let me know how it works for you.
