I am looking to get another N800 (or two, or three), but if it's merely the lack of an access point at work that's at issue, you may want to look for a travel router.

I bought a Netgear travel router on sale last year for $10 (then left it when traveling!) and a Linksys for under $50 earlier this spring (with more capability).

In both cases, you simply plug the travel router into a network jack and it provides an instant wireless signal for you and/or anyone else nearby (you can choose). They're both designed to turn a hotel jack into a gateway for several people with laptops to access the internet.

When I want to use my Nokia Internet Tablet at work, I plug in the travel router, do my thing and then disconnect it. The signal is not intended for long distances and I don't leave it on, thus keeping under the radar. It helps that there's a hotel nearby with an open gateway, so "travel router" as a WiFi network name that shows up sporadically may not be raising any alarms.

Maybe being able to use your N800 will make it something you won't want to part with. :-)

PS: The Netgear has a physical switch that allows you to permit only one connection, which I think provides a good security.
