[wplug] More on downtown WiFi

[Ryan Moszynski]

quote  from P-G:
#############
To log in, anyone with a Wi-Fi transmitter or card needs only click on
the wireless icon, then on "Viewable Wireless Networks," and then
"Wi-Fi Pittsburgh" and "Connect." Users will go through a registration
process and can use the system for as long as two hours free of
charge.
...
The operator, US Wireless, makes money on subscriptions and ads.
...
The partnership is holding free Wi-Fi training sessions next week,
from 11:30 a.m. to 1:30 p.m., at the following locations: Monday at
625 Liberty Ave., Tuesday at Mellon Square, Wednesday at PPG Place,
Thursday at Market Square and Friday at Two Gateway Plaza.
#############

whoever can and is interested should go to one of these training
sessions and see if they can get a linux/bsd laptop to connect.

In the first part of the quote, are they describing how to connect with a mac?

I'm guessing that the "free" service is ad supported.  I'm just
wondering how the ads are handled.
