For a project setup I have compiled some hotspot software.Here they are if you happen to find google not enough:
I have evaluated publicip.net which is a free service. You download an iso and there is a simple setup process which requires box with two ethernets ,USB port, and an Access Point. No hard drive is required as of the of this post. All configuration is stored in USB and you configure your hotspot server from the publicip.net website. This is somehow awkward but this is how they make money if you need advanced services.
