Great I'd love to take a look.

My current idea is to model a 'like' as a payment of one 'like' from Alice
to Bob.  In this way you can extend the principle to a full web payment
system quite easily.

In this scenario there's only one like counted between entities.

I was simply going to allow both parties to keep a record of the like,
notified via a pingback.

There's many possible strategies for sync, an exponential rate limited
approach something like tcp/ip may work as you suggest.  I guess we'll
learn more as we try :)
