Linux WIFI hotspot/internet cafe software

[Tim]

I should probably specify that I don't really want an embedded system for routers, there are plenty of those and they are not hard to setup but I will be running this in a remote place through HSDPA so I want to be able to write scripts to for example restart and reconnect automatically and I would like to be able to remote desktop in to make changes and fix things if need be. There is plenty of Windows software that does this but I really don't want to run a Windows system for reliability and cost.
