That's fine: I did some tweakings too but I'll gladly take and use your
changes... I'm pretty sure they will be more "reliable" than mine, given
your level of seniority here. :)

All of them, that's correct. Our driver also supports Solaris, so I could
eventually also work on Solaris... I just can't commit on that at the

Even if it's LGPL? I'm just curious on why it is so. Is this a GPL problem
or just a legal precaution?

Cool -- it will be LGPL.

Dominant mode is controlled transparently by our driver. If the user enables
it from our system-wide preference pane, the driver will send back
information on just one axis, so it's completely abstracted out from the
specific application code. So, it would be nice if we could do the same and
abstract it out in the generic HID wrappers. It would certainly make my life

That's great. I will probably be available to work on this full time
starting next week or more probably the following, as I will be attending
WWDC ;-) but I'm really excited about all this!
