I'm looking for a product that provides HTML-based authentication in
order to gain access to internet access (wired and wireless).

It's for a cancer care provider and we only want patients to have free
Internet access so that people aren't stealing their bandwidth from
the outside.

The only stipulation is that we'd like a hardware based solution. (No
linux HOWTO type projects, etc.)

Any recommendations would be GREATLY appreciated!

Thanks,

DC
