We try to avoid drivers as much as possible because they are a serious obstacle to supporting new Windows versions and service packs as they come out. I can't comment on VMware's 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. 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.
