[Babel-users] Babel and IPV4

I'm not sure tunnelling belongs in the routing daemon (and yes, I know
that early versions of mrouted used to implement tunnelling).  I think
it is better done in a different program, or natively at the kernel
level.  Of course, Babel has no issues routing across tunnels.

No, that's a different protocol (route autoconfiguration), no need to
clutter the routing protocol with that.

Where are you?

Hmm... has the 800 MHz band been made license-free in the US while
I wasn't looking?

Yes, all of this sounds like the perfect application for Babel: your
network is mostly static and to a great extent sparse, so Babel will
be much more efficient than olsr.  Obviously, we need to implement the
IPv4 support before Babel can be useful for you.

I know I'm going to be very busy until the middle of next week.  I'll
let you know when I implement something.
