The easiest way of doing this is to create a column in the database
that gets checked when the user logins. If the column is something
other than NULL, then the user is logged in and the subsequent login
is rejected. This is the most reliable method that I know of.
The problem with this is when and how to clear the column. I am not
sure if there is a way to create code in CF that would trigger
removing the value from the column when the session ended, but it
might be one way of handling this.
