Ok, so with regards to BTCI (Bitcoin Instant), a realistic goal is to take a snapshot of the Bitcoin blockchain prior to the 1st Aug deadline (where it may fork into 2 or 3+ blockchains). We have performed snapshots against bitcoin and protoshares in the past for Bitshares, so this isn't an insane task to complete in 10 days.
It was proposed that the genesis.json file could be modified to include the sharedrop of the 'BTCI/BTC4' UIA against external BTC holders (mandatory witness upgrade).
