Dear Devs,
Would there be any problem to use nbd (/dev/ndX) devices to gain
btrfs-raid across multiple physical hosts across a network? (For a sort
of btrfs-drbd! :-) )
Regards,
Martin

As a follow-up, both nbd and AoE look to be active.
nbd uses tcp/ip (layer 3) and is network routable;
AoE operates on layer 2 (no IP addressing) and so looks to enjoy a lower
overhead for the performance. Ideal for putting together your own low
cost SAN!
