Gary -

I appreciate the input, but I am well aware of how it all works.  The 
problem that I am faced with is that I am looking for an automated 
system to do this.  The reason why ProxyPass was so effective and such a 
good product is that it automated the process of detecting multiple 
logins, while taking into consideration how a few people may log in 
twice from the same computer, people who are "allowed" to share 
passwords, stuff like that.

With that being said, I am still looking for an opensource solution to 
this problem.  As much as I enjoy using ProxyPass, it's still a hefty 
hunk of change each month, especially when taking in to consideration 
the number of machines that I have it deployed on.
