Re: [Qemu-devel] VNC terminal server?

["Leonardo E. Reiter" <lreiter@win4lin.com>]

The Win4Lin Pro version is not a driver, but rather a high-priority 
Windows userspace thread.  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.

Thanks,

Leo Reiter
