Phil, you have many facts wrong.

> The biggest buzzword today is 802.11, a topic is which the value of something is either a, b or g

I dare you to fine me an 802.11g product.

> But what is 802.11b anyway? It is a standard, with the spectrum regulation on the part of the Federal Communications Commission (FCC) well established. Within the 802.11b standard there is what you could call a sub-group, known as WiFi So, in addition to a higher cost for the cards themselves, you are going to need more of them in order to cover the same area. Also, if you have an existing 802.11b network and you introduce 802.11a radios, you need to bridge between the networks because the radios can't talk to each other. Generally, you can use your Linux box with a regular client card in it as an access point.

Um, no, you can't use a client card as an access point. That's why they are two different devices. You can with a mesh network, but we a ways away from mesh networks being used anyplace other than Florida.

> To clarify, by access point I mean something that connects your network to another network or the outside world, rather than a specific product you buy. If you are in rural Nebraska and only want a fast network for your house, 802.11g likely is a good answer <

Considering that there's not a single 11g product yet on the market, this is a brave statement. :)

you can use a client card as an access point in ad-hoc mode... granted, you can only connect one wireless client to it, but the possibility does exist.

You can use some cards (at least those compatible with the Prism2 driver).

Simply type iwconfig wlanX mode master and it works.

802.11g chips are sampling now. Expect cards by the end of the year.

As for using client cards as an access point, there sure are a lot of networks that run like that. Orinoco cards in Linux boxes seem to be about the most popular access point out there.
