One frequently requested ColdFusion enhancement is the ability to distribute ColdFusion applications without having to provide CFML source. I first demonstrated this functionality in 2001 (before the release of ColdFusion MX), but then we never actually shipped that functionality.
As I first mentioned during my summer user group tour, this is planned for Blackstone. But what I did not mention then, and several of you have e-mailed to asked me about, is that the plan is for all editions of ColdFusion to support this. So, for example, you could write code in the completely free ColdFusion Developer Edition, compile it to Java bytecode, and then distribute it for execution on another ColdFusion server. (Of course, this is the current plan, and plans sometimes change).
