markm: the point is to enable instantaneous payments with lower fees, but to multiple parties. This is just an expansion of Mike Hearn's micropayment scheme that permits payments.  It's friend to friend rather than fully peer to peer, but it's faster and more scalable than Bitcoin on its own because not everyone need to be aware of every payment. Everyone just knows about every payment channel that's established or torn down, as on chain transactions.
