The Command pattern is a true design pattern, while MVC is an architectural pattern. It's difficult to explain how one could be used in place of the other because the Command pattern can be used inside an MVC design/architecture. Similarly, MVC can be used inside a Command.
I believe Brent's original question dealt with using MVC triads throughout an application design. I felt he was on the right track understanding the need to separate model from view, but could benefit from using the Command pattern to encapsulate actions. It would lessen the complexity (and thus improve the scalability) of his application. It's for this reason I suggested ARP. ARP has a good implementation of the Command pattern. Rather than redesign his own framework, Brent could benefit from using one that has a good community around it.
