On second thought, as attractive as plug n play seems, it would be
better to explicitly configure peers.  If only we could make the process
easy enough for Windows users.  That implies that we would need to add a
screen to the LUA gui for LEDE/OpenWRT.   The only thing the user should
need to configure is public IP of the peer, port (will use random
ports), and secret.  In that sense, it is similar to configuring a peer
for Cjdns.  Editing a text config file, however, is beyond most Windows
users. 

I note that the latest project Caleb (of Cjdns fame) is working on is a
GUI editor for cjdroute.conf.
