Tom Jordahl has announced that he'll be presenting a Connect session tomorrow on BlazeDS to The Online ColdFusion Meetup Group. He'll cover exactly what you get in BlazeDS and how it relates to LiveCycle Data Services, and will detail some of the reasons why you might want to use these server technologies. He will also explain how ColdFusion developers can take advantage of BlazeDS in their applications.
This comes at a good time for me too because I'm officially jumping on the Flex bandwagon for production apps with the advent of Flex 3. Just put the purchase order request into the purchasing dept today.
