Yesterday (yes, during my three week holiday) I visited the presentation of a colleague about SOA/ESB with Mule. Since the crowd was mixed, and not everybody was custom to ESB concepts it took a while to get to the more interesting parts… but overall it was a worthwhile presentation; I really think Erik managed to clarify some misunderstandings about ESB/Mule.
By the way, why does every framework tend to introduce new abbreviations? UMO? Unified Mule Object?
