I read messages from a few HIVE users (witnesses I suppose) SMT is not that important anymore, Smart Contract should become the next thing, which makes SMT obsolete, in their views. Now I hope they don't forget SMT in whatever form, but must be decentralised. Otherwise you may find a new home for LEO at the KOINOS chain. From the little we know about that chain, what it tells me that everything can be build into smart contracts, its gonna be fast and its fee-less.

I do hope the HIVE guys pickup the speed, since the speed of LEO should not outpace the changes needed to HIVE.
