If I understand you correctly, once a user has logged in, you don't want them to click on the IE icon or Nutscrape and go to your site and log in again? If this is right, just capture their IP on login. When the next user logs in, make sure that the IP's aren't the same.
This will work to prevent a user opening two browsers to your application from one workstation. But if they went to another workstation, you would have to check for username and password as well. That is, in addition to keeping track of their IP's, you would need to make sure that two people don't log in under the same username and password. Now that I'm thinking about this, the above works if your users have a public IP address. In some cases, you might run into users that use DSL in which they receive private IP's on their LAN, but use the DSL Router's IP when they go out to the internet. In this case, you might run into two users from the same company that have the same IP address. This is something to consider.
