Just out of curiosity, do you have any thoughts on DynamoDB, or have you played with it? Not as a "would you replace what you're doing with DynamoDB" but more a "heres a niche where we think it would work really well"?
I know it's very new so I haven't seen any advice on it, where I don't think I've ever seen a pro-EBS point of view from people with non-trivial experience with it.
Speaking theoretically, Dynamo is some really clever tech built by some very smart people -- it's clear that Amazon are using something very similar internally, so it must work in practice. Beyond that I've no direct experience with it or its performance profile.
If I had a very large, rapidly-growing key-value application and a shortage of experienced ops engineers that made maintaining my own solution impractical (e.g. a cassandra cluster) I would look hard at dynamo.
However, as a matter of principle I am very suspicious of the lock-in that comes with proprietary solutions, no matter how clever. We try not to buy cloud services that only have one vendor.
