one immediately obvious solutoin to that is for each routing node to set
up encrypted tunnels to other routing nodes that they want to accept
route updates from - and configure zebra (or whatver) to ignore packets
that come from any other interface.

alternatively, hack decent encryption into zebra for use on insecure
networks (it's been a long time since i looked at zebra, it's possible
that this may already be there. dunno).  this is more work than tunnels
but is probably the Right Thing to do in the long term.

dunno about that.  small wifi networks wouldn't give anywhere near the
same bragging rights to these losers as even a small site on the 'net.

sure, there'll be some - but i can't see that we're going to have to
worry about hordes of them.  for one thing, it's a little close to home
- you have to be in range of the router you're attacking, which
minimises the number of people who can attack any given router node.
