I have heard requests from developers using ColdFusion and Flex that they would like more information about integrating the two. One of my coworkers Tom Link started a blog and his first few entries cover ColdFusiona and Flex integration. His first three posts cover the following topics

• Integrating Flex Applications with ColdFusion User Security
• The Facade Pattern and Using a DataGrid with ColdFusion
• Passing a Structure to ColdFusion via Remote Object (Flash Remoting / AMF) Bidirectional Binding

Some fellow CF/Flexers have developed a site as well.. http://www.flexingcfmx.com
