Wifi Hotspot Server

Hey guys.

I have a quick question. What is the most functional hotspot server software
you have used?

I am looking for something that has the features of something like firstspot
or zonecd but I dont want to have to use a remote server to authenticate
users. I need the entire server software and userbase to reside on the one
machine if possible with a dns, dchp and captive portal etc.

Bandwidth managment and throttling would be essential.

What do you think?
