It would be great, if we can agree on a way to use the existing CLC handshake for SMC-D via virtio-ism and ism-loopback. In that case SEID needs to be unique per hardware instance, cannot be increased and can only be changed for x86 in a non-colliding way. An alternative would be to define new a SMC-D(?) protocol variant/version, where we are free to define new fields (e.g. UUIDs).
