Hi David, Yes, that is a cool option and I've seen it before too. If I had the time, I would have run NetMon on my laptop and try to figure out who they do it. I do know its MAC based, so once you make a selection, your MAC address determines the type of IP address you get. If anyone knows how it works, let us all know! :-) Thanks!

They had thier internet serviced by Cisco, in each room. a small cisco router (this was at the Fairmont, I forgot what model it was, but the Hilton just provided cat5 cable) but once connected to it, you are automatically connected to a webpage (this is the hotel's service aggrement and internet access choices). You have a choice to either be behind a firewall with a private ip or a public ip with no firewall protection. I thought this was a good idea to provide such a service and delegate the two types of configurations to the guest and contractors with no administration needed but I don't quite understand how this can be done? Thanks for you answer again.
