Any tips on where per-packet antenna selection could be pushed?

[Zach Sherin]

I'm not sure I know exactly what you mean by per-peer. Do you mean
that the antenna switches only when we're delivering to a new
next-hop? I would absolutely be fine with that, by per-packet I do
actually mean selection based on destination/next hop so aggregating
deliveries for a single peer would be even better.

Also, I forgot to mention that this is intended for static mesh
networks, so I'm not worried about moment-to-moment changes in peer
location.

Thanks,
Zach
