In case bip110 results in a chainsplit, we've designed a tool that will let you sell off the coins on the chain you don't like, for more coins on the side you consider valuable. Atomically. On-chain. Re-play protected.

This is a regtest demo: on the left an initiator splitting their coins and publishing an offer to sell B110, on the right side an acceptor that wants to sell BTC:
