Its a pretty cool thing; Elliot pointed it at me the other day. It may make sense as a bridge in future, or we may want to migrate over stacks entirely (but I couldn't argue that 0mq is what we need clearly and unambiguously today :)). As a project I think we're still getting our heads around eventual consistency; thats a pretty core change on its own, and until its sunk in we'll find it hard to really reason about things. -Rob _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
