Right -- I do the same here with a dell latitude d830 for development
and testing.

You will need an access point, and a usb-ethernet adapter.

The existing ethernet on the laptop is automatically configured to be
eth0 -- which is set to handle the Internet/WAN connection. Add the
usb ethernet and it'll be autoconfigured as eth1 - the LAN connection.
Hook that up to the AP.

usb-ethernet adapters bottleneck really easily, so if you more than a
dozen or so XOs you will want to swap the roles -- the embedded
ethernet as eth1 and the usb-ethernet as eth0. To do that, use
xs-swapnics.

Details on how to do these thigns in the
http://wiki.laptop.org/go/XS_Techniques_and_Configuration page.

Not really. In some cases -- very few actually -- the wireless card on
the laptop may have what is known as a "hostap" driver. If your card
is one of the few that does, you may be able to run it as an access
point.
