You could start with the excellent GPL project WiFidog 
(http://dev.wifidog.org/wiki/About). It supports the 
centralized/decentralized approach for many hotspots, SSL, automated 
signup/authentication, and runs on the Linksys WRT54G router as 
firmware, or on Linux. You'd have to add the ad banner part yourself - I 
suspect that's all that is missing. And I'm sure they'd love it if you 
contributed your code back to their project. I've used their hotspots 
many times (part of the Île Sans Fils free wifi project in Montreal)... 
might save you a tonne of development time.
