Thomas, I personally don't know, but I know someone that would. You need to talk to Gordon Potter. [log in to unmask] campus_phone: 607-255-8061 He is a professor at Cornell University and I think he studies/consults on these types of issues often. He is always interested in hearing about real world issues. Hope this helps, Heather Cottingham -----Original Message----- From: Lepsche, Thomas G (NM75) <[log in to unmask]> To: [log in to unmask] <[log in to unmask]>
