Question about accounting software and security in cybercafe.

[Pall Ioan <paul () elsig ro>]

 Hello, 
I would like to post a question regarding an optimal and secure distro in a public cybercafe. Which would be a good 
choice for making a *nix only network in a cybercafe? And regarding a security, how could I improve it, make it secure 
enough to allow the client to access securely the internet? The main programs would be a mail client, web browser and 
chat (im) clients. 
And does exists a server-client applications which can do accounting and automatic login/logout from a dedicated server 
for the clients? 
 
 Thanks in advance, 
Pall Ioan
