Data view datasource from outside of dmx

Anybody know if it is possible to set a data view component’s data source to a javascript array generated outside of dmx?

Without going into all the reasons leading up to this, it would sure be handy to be able to set the source of a data view from javascript. I’m using a custom formatter currently which works, but the formatter constantly runs in the background. The formatter either calls a filtering routine when needed, or just returns the already filtered array.
