The wifi faq has some good info mixed in there, but one thing I think it is definitley missing is some basic explaination. That's probably the best thing for newbies. Now, first off, I'm probably not the best choice for writing it because I'm not exactly the most informed on the matter. But perhaps someone should do a little writeup assuming zero knowledge. Basically just explain how it works to
a. wardrive
b. use your own wireless network for transferring files and such
c. Use cellular service to access the net
d. as wiredex said I beleive, use a wired network solution

just a basic description. Noting what equipment is needed for each, where it can be found and a couple suggestions of what qualities to look for in each. Then a brief summary of the process. IE you attach wireless antenna to your car and if you are close enough, you may be able to pickup the signal from starbucks and use it to access internet. The signal is sent out via. . . . Stuff like that.

I think a nice organized description of those things would be awesome for people new to the scene.
