Hi, there people!

I have a project I have to deliver but I am at loss on the relevant tech. to use although I am a predominantly vb.net guy. The VB.Net is the 2008 one.

I am to deliver a software that would enable an internet cafe do these basic things.

* Issue tickets that enables users to login and use any computer system on the network to browse the internet.
* At the expiration of the time bought (via the ticket) the computer screen is blocked to further usage and the login page is displayed.
* On the server, We should be able to see the list of connected or logged in users and the usage time remaining
* see the list of websites being visited by each of the computers
* Ofcourse if i'm able to do the above, I can report on daily sales and so on.

So people what is the overriding tech to use. I know it a client and server app. Thanks in advance .
Ideas are welcome.
