Short answer: yes.

Any DOCSIS-compliant cable modem is capable of doing that, but not all providers will allow you to take up multiple public addresses without fussing. They'll either stop you by limiting one IP per MAC address or by mailing you a copy of your contract along with a cease-and-desist.

BTW, I can think of no reason why a switch wouldn't work instead of a hub.

Verizon allows multiple users accessing a DSL moidem.

I'm doing it at home. No problems.

I haven't read all the posts but you NEED to make sure the router and access points you use are VLAN compatible. If one of the clients can see another clients laptop then the business owner could be liable both civilly and criminally. There are federal regulations governing public Internet access. Netopia makes a router/hotspot package that will take care of this.

yes, but it's probably using NAT to share your one public IP amongst your computers.

If one of the clients can see another clients laptop

I know what you are saying but I never heard of that. Matter of fact a guy with kiddie porn on his laptop was busted exactly that way in a hotel here recently. Seems another guest was able to see his files and inside a folder named "Dave's stuff" or something like that. The guest called police who went through the hotel's guest list and busted Dave who was a commercial pilot on layover. So it would seem from what you are saying Dave has civil recourse against the hotel.

My point is that I doubt that anybody knows about any federal regulations and this was a Crown Plaza. If you are smart you know enough to turn off file sharing.

Its called AP isolation; most basic wireless routers have this now. Anyway, how the heck are you supposed to create vLan's with wireless clients. Generally, vLan's are created by rules as packets enter and exit ports on a supported switch or rules applied to known MAC addresses. The integrated wireless AP on the switch is seen as just another port of that switch.

Federal Regulations. Please post I'd love to read them.

Turning off file sharing. Maybe. However browsing someone elses files on a network its quite simple with the right tools. Just remember; that no network is safe, if it was soft coded then it can be decoded, plain and simple. Wasn't it recently revealed that the chinese had been poking around the pentagon? I assure you the pentagon uses more security than just enabling windows firewall.

Agreed. One should never assume that their files are secure on a public network.

Probably one of the easiest and cheapest ways to do this would be to simply pick up one of the wireless units from Linksys:

WAP54G - Wireless 802.11G Access Point
Should be able to do everything you want it to, simply hook it up to the modem or another network switch to get internet access, configure the settings, and you're done.
WAP54G on Amazon

WRT54GL - Wiress 802.11G Router Open Source Edition
Great little unit from Linksys that lets you run a custom firmware to do basically the same thing as an access point for less money. DD-WRT is one such firmware that works great for using the router as a wireless access point.

Yup, sold plenty of those routers. That's where I got the idea from.
