Does the kindle web browser proxy through amazon when using wifi? If so, giving information to enable tethering (using the kindle as a gateway to share kindle internet access with a PC) would be a "forbidden topic" at this website, because a tethering solution that gets through the amazon proxy would also work for 3G access (which violates the amazon TOS and may be illegal as well).
In fact, even if you use tethering legally through wifi, if you kindle supports 3G and wifi drops out, it will automatically switch to 3G and you find yourself getting into troublesome areas completely unaware of the situation.
So... this discussion on tethering can easily get into "gray areas" of legality (and beyond)...
EDIT: However, if the kindle wifi connection does NOT go through the amazon proxy, then this is a non-issue (so you can disregard my warning, in that case). 
Just be sure of what you do and how you do it.
Devs: does anybody here know for sure whether wifi connections proxy through amazon, and if there is any warning before a tethered connection switches to 3G when the wifi is lost?
Basically, what I want to know, is there a SAFE way to do wifi-only tethering that WILL NOT go through the 3G connection when the wifi connection is lost? If not, we cannot support tethering even for a "wifi-only" connection.
