Guest fees/Authentication

[Matthew Irsik]

I realize that this is not a very technical question, but the 
University of Utah is switching to an authentication/log in system 
for students, staff, and faculty  in our labs.  Does anyone have any 
info or can put me in touch with any schools, labs, or administrators 
who are using any kind of a "guest" system that handles non-student 
users?  We are having a huge debate on this subject, so any comments 
would be very welcome.  Thanks.
