Markus' implementation doesn't currently do any attempt at link quality
estimation, so any pybabel-pybabel link will be treated as if it didn't
suffer any loss, which will cause long and highly lossy links to be
preferred.  I'm pretty sure that would break Dave's network, we'd need to
test in a somewhat less hostile environment.

As to wired nets, the only limitation I can see right now is that pybabel
doesn't disable the Linux kernel's uRPF filter, so unless you remember to
do it manually, you're going to get transient blackholes.  I'll hopefully
be able to tell you more once I've finished reviewing the code and done
some testing.

By the way -- what Markus has written is some compact, elegant and
comprehensible code, and the comments include pointers to RFC 6126.  If
you grok Python, and if you're the kind of person who understands things
better by looking at code, his is the implementation to look at.
