Tim,
>Then what you are suggesting is to keep properties in the biz obj that store the results from the gps event and notify the form via the state changed event. The form can then if listening, retrieve these updates via the properties in the biz obj. Correct?

>I am beginning to wonder what will happen to performance. My gpstoolkit fires a position update event constantly. I have a wrapper class that recreates an update object and then fires it's own position update event the biz obj listens to, then the biz obj fires a state changed event. Should this be a concern?
I recommend trying it out to see what your performance is like. Is it an option to ignore a percentage of the events and only update occasionally?
