The Win4Lin Pro version is not a driver, but rather a high-priority

because they are a serious obstacle to supporting new Windows versions

approach to be honest.
I will say that using a device that has readily and/or publicly
available drivers is probably ideal, such as a Wacom tablet. We are
trying to move to more of a device model on Win4Lin Pro for
performance reasons, which is why I am interested in this approach.
But letting Microsoft maintain the guest driver, if it's built into
Windows, is the best solution. It also guarantees the broadest
possible guest support in general - whether it be Linux, Mac OS X, etc.
The driver isn't built into Windows. It's pretty easy to install though
and the way my patch works, the PS/2 mouse is used until it detects the
tablet has been enabled.
The Windows driver uses quite a bit more of the features of the tablet
than the X driver so there's a bit more work to do but nothing
extraordinary.

If anyone has a link to Anthony Liguori's driver, I'd be glad to look
into fixing whatever may be wrong with it and posting the patches.
Thanks,

I thought Anthony Liguori had already written a Wacom tablet emulator
for QEMU and that worked fine except it supports only one button. I
don't remember if this support was complete and I don't have a link to
the patch.
With this you don't need to disable mouse acceleration in the guest OS
because it makes no sense to accelerate a tablet.
On the other hand writing a guest-side driver for QEMU would leave
room for further improvements like hiding/showing or
grabbing/releasing the mouse at specific moments. Or, possibly reusing
tools from Win4Lin or VMtools from VMware.
