This is something I've been meaning to ask, and also how many are
standards complient themselves?  I *think* some of the Linksys and D-link
units support some form of WDS.  My guess is that the Netgear MR314 is too
old to have this feature, at least with the base firmware.

Same, and also same essid.

wlan0 is to/from clients connected to your Linux AP.  wlan0wds? are
connections to other APs using wds.  I'm not using bridging but I think
you'd use bridging to combine wlan0 and wlan0wds0 into br0 and use br0 in
place of both of the above.  Anything going out br0 would be transmitted on
both of the other interfaces and anyting coming in on either interface would
be re-transmitted on the other.  Someone correct me if I'm wrong on this
last bit.

Since they are both phisically on the same card then they would have to be
in the same mode and channel but that should happen automatically.

Here is the relivent part of the output of ifconfig on one of my machines
(but remember I'm not using bridging).  I've pre-assigned 5 wds links and
for some reason hostap seems to use wlan0wds4, then wlan0wds3 etc. rather
than starting with wlan0wds0:
