Good question.  It seems that defining and configuring a session limit by application or product could be a matter of setting up a database table/maintenance program or configuration file for that purpose.  The harder question is how to enforce it.  It seems that the application server would need to know precisely the number of active sessions.  Active sessions would vary as new ones are established, inactive ones expire, while others may be canceled by user's clicking an "exit" link.  Can that be done?

Not sure it should be a constant, unless an ISV would like to enforce a user-based license restriction, which seems reasonable to me.  Like, I know my web application is hosted on a server and could be used by an almost unlimited number of users, but if you want unlimited use, please pay more.
