This will allow BitShares to utilize the increased speed and power of the EOS software without needing to buy EOS tokens or give up their BTS.
In order to obtain BEOS tokens, BitShares or BROWNie.PTS tokens must be transferred from the BitShares chain to the BEOS chain using the cross-chain transfer gateway described above.
Why should anyone risk his BTS by sending to a centralized place, remove voting weight, selling BTS for collateral reduce, when we can just sharedrop on the BTS wallets? With this sharedrop method I have to decide between BTS or BEOS.
Do we realy need an extra chain to be compatible with EOS? I don't think so.
An extra layer on the BTS Network can also provide compatibility with the EOS network. Starting with cross token exchange (atomic swaps) and multi coin wallet, than utilizing side and private chains.
The average Joe doesn't need/care about smart contracts, it has just to work and be easy to use.
