Very cool. I'm jealous. :)
Though you won't get the benefits of dietary iron with the enamel coating.
C'mon Sushi, cast iron is relatively easy to clean when you don't have a dishwasher. Just wipe it, rub in the salt, wipe out the salt, and break up the chunkies with a few passes of a steel wool pad, and you're done.
Plain ol' cast iron's got a bad rap... Treat it good, and it'll treat you good.
