I will be speaking at the MXimize conference in Boston Sept 20-22. My topic is: Under the Hood with CFCs - UDFs, CFCs, Web Service and Remoting. Here's the abstract:

ColdFusion's UDFs (User Defined Functions) and CFC's (ColdFusion Components) provide a strikingly simple, yet incredibly powerful method for crafting applications. Learn the power and limitations of UDFs. See how to unleash UDFs by packaging them in CFCs. Turn CFCs into Web Services and data sources for Flash Remoting.

Hope to see you there!
