For the benefit of those who haven't tried this, sending one or 
two broadcast pings to the subnet is one way to find your neighbors,
but that doesn't seem to work using windows (or cygwin).
I guess the arp table didn't help? (I don't recall the Windows 
command to see it).
This seems like a silly problem to have, but I don't know how, in 
Windows (even with cygwin) to find the IP of that node you know 
is right in front of you.

BTW, older images (certainly the SSID cuw ones) will not have the
169.254. alias, but will be reachable on 10.0.

Hmm.. that sounds like maybe it's still trying to use the serial 
port as it's console, but the recent published ISO images should
not be doing that.
