Ted, I am not sure I understand the problem with the fixed number of components. My understanding is that CM prefers immutable objects. Adding a component to an object would require reweighting in addition to modifying the component list. A new mixture model could be instantiated using the getComponents function and then adding or removing more components if necessary.

I think that the limitation to a fixed number of mixture components is a bit limiting. So is the limitation to a uniform set of components. Both limitations can be eased without a huge difficultly. Avoiding the fixed number of components can be done by using some variant of Dirichlet processes. Simply picking k_max relatively large and then using an approximate DP over that finite set works well. That said, mixture models are pretty nice to have.
