I apologize for the delay. The developer that knows this product best was on vacation until this week, so it took me longer to get an answer.
We do want to port the ListBox towards the Phone SDK, and by doing this we will have to implement touch support and gesture support for scrolling, navigating and using the buttons and controls that are part of our default template.
So yes, it is in our plans, however we do not yet have a date in mind as to when it will be available, but it is one of our priorities.
However, you mention multi-touch. We do not think that we will implement anything in regards to having multiple touch points. There will therefore not be support for zoom in/out.
As to doing this yourself, we would recommend the following blog post:
You could therefore subscribe to the Touch event and pass the ListBox Panel as reference point in order to track the touch points and scroll the ListBox, etc.
As for the interaction with the buttons and controls that are part of the ListBox, you might have to derive from those controls and change the control template of those we use for the corresponding derivation, also listening to the touch event, but in a more specific manner.
** Quick Tip: Clients with an active support subscription should be sending their questions by email if they wish to benefit from the faster response time. Thanks!
