If it really is an AP, it won't do the job, as an AP cannot be a client 
to another AP. 802.11 DOES have the concept of a wireless backbone, 
called WDS (wireless distribution system), but it is not yet defined 
(Work In Progress: 802.11s, I am a contributor to the security 
features). So each vendor has its own WDS implementation (MIT's OnePC 
implements part of draft 1 of 802.11s).

Of course there are devices out there that are referred to as wireless 
bridges (Linksys WRT54g is one) that act as a client and bridges an 
ethernet as a single client to the AP. Note that a wireless bridge is 
NOT an AP. Of course there are probably devices out there that can be 
configured either way....

Note, I work on the 802.11 standards and know them well, but I don't 
know of all the flavors of implementations out in the wild.
