this is interesting, but I wasn't happy with SQS so i'd be wary before we started using something like this over a custom notification system on top of RabbitMQ. we used SQS for a while but kept having problems with polling - deleted messages would reappear with alarming regularity (which to be fair is documented by Amazon as a design tradeoff due to the distributed nature of the queue) - but it really caused a hassle to build a system that could handle these duplicate messages, especially when there was a lot of work to be done per message.
