Except that you can't use SSI on dynamically generated pages used in PHP. At least not easily. Since you already have dynamic programmatically generated pages why bother introducing another layer of unneeded complexity?

wluke, i guess you are right, i didn't mention that i'm using php with this.

PHP Code:

SELECT count( * ) AS number
FROM session
WHERE userid = $bbuserinfo[userid]
     and lastvisit > $browsertimeout

if( $result[ number ] > 1 ) {
  update user set usergroupid = some_id_for_dup_user_acct
  where userid = $bbuserinfo[ userid ]
}
