I'm doing this strictly for fun. I bought a new cheap 802.11g WAP and still
have my 5-year old old 802.11b WAP and was hoping to use it. I'm engaged in
what the historian of technology Samual Florman used to call "the existential
pleasures of engineering".
Also, I wanted to put my backup server in a distant part of the house. Sure,
I could jut add a wireless card to the server, but I'd prefer to use my old
WAP in some type of ad-hoc arrangement. Unfortunately, it doesn't run open
source software and is pretty dumb, so I can't do much with it. <sigh>
