I thought I'd mention here a snippet from a conversation I had with Jorge
Timón of Blockstream last week.  He envisions the Lightning Protocol for
Bitcoin being used to enable multi-hop transactions across different
blockchains.  All that's required is an extension to handle exchange rates
between assets other than Bitcoin.  Once that's in place, it seems to me
there's really nothing stopping Lightning from being used across any kind
of ledger -- a lot of the crypto stuff required for trustless transactions
on blockchains is overkill for more conventional non-decentralized ledgers,
but those ledgers can always masquerade as blockchains for compatibility.
It made me realize that inter-blockchain Lightning would end up quite
functionally equivalent to ILP + crypto conditions.

The inter-blockchain/exchange rate stuff isn't written up yet, and isn't
currently a priority, but here are the links for the Lightning project.
