The situation

An organisation I work with has members who need access to a computer and access to the internet. For example, to type a CV and then email it out.

The organisation only has one computer available for use by these members at the moment and I notice that one or two people tend to hog the machine all day.

My Proposed Solution

Install “cyber cafe” like software that can handle multiple log in accounts to manage the large number of users by:

• Keeping a log of who was logged in at what time
• Restrict each user account to 60mins computer use per day after which you are locked out of the system until the next day.
• Access is free so it does not need to contain any billing software.
• An "Admin" account would be able to log in to add/remove users, add/remove mins from a user, check logs etc 
• This is a stand alone lone ranger machine so it will have to act as server, client kila kitu. Hopefully we can replicate this solution in the field offices outside Nairobi.
• The computer will most probably be running Ubuntu however, this is flexible. 

My Cry For Help

Does such a solution exist? Please share if you know of any. Even better if you have built one or implement such solutions.

Also considering the situation is there another better way to tackle the problem that I am over looking?

Thanks
