One thing I’ve been thinking about is the ability to have value providers - not only for commands but for other things like parameters on queries and such.
Typically you could have a value provider that points to anything, such as a query string parameter in the browser or a factory that gets called to create the value - typically for unique IDs or similar.
When we fire off the command, we create a copy of the original one anyways, so my guess is that it is for the values that change and a good way for describing the value source.

- We want to be able to how the command can be put into a "new" state. Typically, you want a new commandId (rather than reuse the same one!), you want a new Id created for the entity you are adding, you want any constants set on the command (e.g. if adding a new contact to a supplier, you want the supplierId set).
2. We want to reset the values silently, so that validation messages do not appear.

Yeah, my first thinking was that we have a Init(setup) method where you pass in all the actions you want to be performed when getting a new instance. We first reset everything in the command and then apply the actions provided. I sense you have a more comprehensive approach though... :-)
Your senses are right :) I think it could be a less obtrusive one as well, not sure yet.. But the idea is the same.
Could also be something like
…
myViewModel: Bifrost.views.ViewModel.extend(function(myCommand) {
myCommand.someProperty.populatedBy(function...)
myCommand.someProperty.populatedFrom(.. another observable..);
});
Something like that.. Not sure yet..
