I would be careful however because keeping the dialog open keeps message information about each message in the system so that the service broker can ensure that the same message isn't send on the same dialog a second time. I could see this having a performance problem and potentially a storage problem depending on how much data is kept around in the database for a received message on an open conversation.

Just a follow up to the service broker discussion. One of the questions I asked was about balancing creating dialogs vs the amount of messages you send. Just wondering if you have seen this post which talks about the overhead of creating conversations. http://blogs.msdn.com/rogerwolterblog/archive/2006/05/20/602938.aspx Hi Denny,
