They take an interesting approach to wireless at my office. Rather than having a WPA password that they have to distribute the wireless is fully open. However, it is outside of the firewall in the DMZ as they call it. So, if you connect to it in the office you can surf the web and such, but can't get to the internal stuff. If you want to do that you have to use the VPN. Of course, the VPN is secure end-to-end so even though the wireless is open, the traffic is encrypted.
I am aware of several places that do this. However, if you are talking about a reader I doubt it would be able to run the VPN software.
Anyway... I think the security risk with a WiFi device... assuming they are running WPA is weeker in the device it self. You steal the reader you've got access to everything on it. These things don't have security at all from what I understand. So, unless you are talking about ONLY using it as sort of a dumb terminal browser I don't think it would be the best choice for a portable browser device for say a Dr. or Lawyer's office.
