At the [JAOO][1] conference in Aarhus, Denmark I was able to co-present with [Josh Holmes][2] from Microsoft about the Architecture of RIA. This presentation was technology agnostic so we didn't talk about specific implementations using platforms like Flex / Flash or Silverlight. Josh has posted the presentation slides and detailed notes on his blog:
