This is true. However, with one AP, it works great. Multiple APs are
supported by the Linux hostap driver.

No. WDS mode is used for repeaters, not for roaming between APs.
: Your only options are:
: - route instead of bridging: this requires 3 subnets (one for each LAN and
: a /30 for the wireless link), and IP forwarding enabled
: - set up some form of tunnel
: - a specific case of the above, setup an IPsec VPN between the two boxes.

: Note that the latter options probably require some sort of routing too, or
: you'll need to do some fun things with proxy ARP or promiscuous mode somehow...
I'm not sure that I follow this advise. It seems to not match with
the setup that I'm running right now typing this in.
