TD with Multi-Touch OSX solutions?

Hi All,
Any of you folks using Multi-Touch Monitors with TD in OSX?
I’m gearing up for teaching a workshop, but the lab is all Mac Pro 6,1. This seems fine for TD, but not so good for multi touch TD, as Apple doesn’t support Touch Screens in OSX. There is a 3rd party driver from a company called Touch Base. Their Universal Pointer Device Driver (USDD) sells for $179 dollars In the USA. Supposedly it works well, once you get it working. I had limited time to test it in the Schools Lab today, and didn’t have any luck with a Temp/Trial-Driver from Touch Base. I’m going to try again later, and will report back. Also $179 for each seat is pretty steep as well… soooooooo…

I’m trying to find out what monitors people are using, and what Driver solution they came up with. Also listing any problems would be really helpful. Oh and do you get all ten fingers working ok, and showing up in the Multi-Touch Dat?
And is there a better way… other than PC’s?

Thanks so much!
