Our restaurant has DSL and a wireless router that we use internally. We'd like to add a public hotspot service to it. What would this require besides gateway software with credit card billing? Can anyone recommend the software we would need?

Give the customer the passphrase to the router when they order something (to stop freeloaders). The customer will have a much 'fuzzier' feeling about you this way then trying to gig him another few bucks to check email while he waits on his sandwich or steak.
To your specific question take a look at this:
see if this fits your needs, note I've nothing to do with this vendor.
