iscsi loopback of a logical volume

fellow users
probably not exactly for lvm list but I hope somebody could share an advice or two.
I've looped back my LV and I thinking of best way to mount that iscsi device. I though UUID would be natural choice but it's exposed twice in this case and I'm not sure how kernel would act. If you have your LVs as iscsi loopbacks how do you mount them?
I thought lvm via iscsi was a good idea, is it?

many thanks
