Answer 1

Use a database table to store the number of logged in users but you need to come up with some way of imposing a time limit on those users. I would suggest a field in the table which notes their last activity. When a new user attempts to login you need to apply some logic like this (pseudocode):

if(<10users){
    login
} elseif(any of the users have no activity for 30 mins){
    remove that user and login
} else {
    inform user of no space
}

You would need to update the last activity every time a logged in user visits a new page.
