I suppose that what Matt was referring to, when talking about stateful CFCs
scalability issue, is that you cannot use session replication if you put CFC
in session (because for the moment, CFC are not serializable).
No, that's not what Matt is on about. Session replication is nothing to do with scalability, it's more about robustness, availability and fail over. In fact, real-time session replication may actually make it harder to scale your application due to the increased network traffic between servers.
In 95% of CF applications, session replication capabilities is not a requirement.
Agreed.
The best example is macromedia.com which extensively uses CFCs on the "model" layer (with View as ColdFusion pages or Flash applications). I suppose they also use CFC in session scope, don't you Sean?
Yes, we use CFCs in session scope. We use CFCs in server scope too (we don't use application scope because we are the only application on our servers!). We use CFCs as controllers and as facades. And of course we use CFCs for the model.
