Everyone: we talked about this on IRC and I'll elaborate on this for everyone's benefit: Once a particular consumer of the queue gets a message with a particular group_id (this is initernally managed, the consumer doesn't know anything about this stuff), it'll be the sole recipient of messages with that group_id as long as it's still connected. So in my scenario, the producer is always going to use the same group_id. This should handle the edge-cases I referenced. It'd be nice to have a feature to kick-off a consumer that you don't want consuming any more but that's not possible.
