SNIA did start a discussion on this, but AFAICT, the project dissolved into a lot of internecine sniping between vendors. RFC 3721 provides this service for iSCSI, but not for "traditional" FCP. I suspect the same approach, appropriately modified, might work fairly well.
Another good reason to use iSCSI, IMHO.

Bleagh. Please, no. Fix the problem, not the symptoms.
