I can see how this would help, but I do think we need to consider the likely performance trade-off for persistent messaging very carefully in this solution. It's hard to make persistent messaging really quick anyway (or at least other messaging vendors find it hard :-) so we'll need to test comparatively so users would understand the 'cost' of replay-ability.
I think that users make the messages replayable in some other way if the messaging system does not support this (e.g. slap them into a database before putting them onto the queue is an obvious example...). That is almost certainly more expensive in terms of performance than the messaging system making them replayable via its store implementation. RG
