It does seem like this is a really good solution. Just let ENG/BEE be 1:1 tradable.

I understand costs for things... but i'm not sure why there had to be another token. Why didn't you just keep the token as ENG on hive-engine and let users transfer over. If they destroy the token on steem-engine it could appear on hive-engine.

We have a bunch of ENG we would prefer to be on Hive.
