Just to be difficult, I have noticed a small linux based AP that had
ethernet and two wlan cards, the idea being you link to the next AP up
the foodchain with the other wlan card.

I really dont like that idea at all. I dont think most boxes would be
robust enough to handle the leverage a wind loaded omni could generate. I
know signal pwr doesnt grow on trees but a small length of cable like a
pigtail isnt going to have a dramatic effect on what you get to the
antenna.

In WA some people have those cabletron ruggardized APs in remote areas,
these seem to hack at least 60 degrees.

The need for CF-IDE would be obviated by these new boards with the onboard
pcmcia and CF adapters, assuming they decided to make them bootable in
bios.

Someone made a mention of using ATA flash, and I cant find the message
right now...

If you look at how distros like gibraltar run I cant really see them
wearing out the CF in any hurray. When boots it unpacks a ramdisc into ram
and largely works out of that. When it shuts down it optionally alters
these before shutting down. While running there is no writing done to the
disc.

It is a quaint australian custom, just dont get used to it, maintain the
rage =)
