Rick,
As I mentioned, I will try to tease out the actual requirement from one of the end user groups.  These are products coming from a company I am in touch with over in the U.K. I have not seen a demo but that may change based on if the user group wants to set one up. These are non-descript slick sheets, but it shows what they are attempting to accomplish.

Let me know if you have any questions you think I can answer.  More to follow as I get more information.

Thank you,
Chris
