This becomes escrow router

Yet another ethereum scaling solution is launching a test network.Announced Friday, Liquidity.Network is officially joining Raiden Network as the latest ethereum project to attempt to move transactions off the world's second most valuable blockchain and into payment channels, in turn, allowing the network to support greater adoption and use.

A couple of start ups will be doing web based pipeline control. Theory will say they all resolve to a timeout based market to resolve loops.   The revoke fee is priced to effectively remove payments loops by first come, first serve.  Loops thus resolve.

The concept is good over any ledger with revoke under timeout, which is basically all of them, including real delivery ledgers. The escrow layer becomes distinct from ledger layer.
