BEOS is also legally well design and set. I do love the membership part. Token portability and Jurisdictional Agility are great features. So many Start-up, COOP & Not-for-profit organization can benefit from many things BEOS will be offering from Bitshares. I see BEOS as an EOS sisterchain like Worbli or Telos, only that it already have many businesses running on Bitshares that can move to this new chain if they want. The challenge IMO will be to build a strong EOS development team around BEOS. For now, lets just focus on selling the "rainfall" opportunity to those wanting to join a cool project.
