Active/passive fail-over à la Linux bonding would work for me too. The
biggest disadvantage of that is that you waste half your available
bandwidth, but that probably isn't a big deal for the Atlas Anchors.

It is quite possible to create a setup that does 802.3ad if an LACP
neighbour is detected, falling back on active/passive fail-over if not.
That said, you do lose most of the error detection capabilities of LACP
that way. Quite possibly not worth the engineering effort if it's not
already implemented in whatever software you're using.

I'd rather you spent that time implementing LLDP support, come to think
of it. (That would be useful on the non-Anchor probes as well.)
