Me, too, with each of Camino, Firefox, Safari, and Mozilla.

How do they make that determination?  Cookies?  What if the client purges
them?  IP address or domain name?  Well, I'm trying from a cafe.  A little
probing shows my apparent address to be:

    c-67-172-156-57.hsd1.co.comcast.net [67.172.156.57];

Does that just mean that someone else connected via Comcast before me?

Www.zoomerang.com discloses nothing about their technology.  Maybe they're
not very proud of it.
