Sure: the clients mounts the inner squashfs readonly, but in order to
bcache get working, the nbd-server must export read-write, or at least
with copy-on-write flag, to let the bcache layer on clients work
throught nbd device

Anyway: problem solved. Performance is not noticeabilly increased, due
to obsolete hardware in clients, but network load improvement is really
good
