wifi hotspot software needed

[keith kouzmanoff <keith () kouzmanoff com>]

I am consulting with a new player in the internet field and I am looking 
for suggestions for hotspot wifi software.

GPL would be great, but I know some of the stuff out doesn't have all 
the features.

http://www.antamedia.com/ looks pretty solid and has an oem feature, 
anybody else us this?

We will wanting to set up about 10 different hotspots in a small 
downtown area and we want to give away the service for free. Doesn't 
everybody expect that already?
I'll want to also be able to manage some rotating-commercialized 
popups/popunders or log in advertisements to offset the costs.
As well as some traffic shaping / blocking some common high bandwidth 
usage sites / or times of the day /  for the neighbors who live in the 
area too.

Maybe some one has done this before? If you have any suggestions, please 
feel free to contact me off list.
