Sliding through a table

Sliding through a table

I'm designing a an app that will be viewed on a small embedded pc which only has a touchscreen interface (a Chumby actually). 
One of the things I want to do is to allow the user to scroll through the current audio playlist by tapping on the screen and sliding the list up or down.  I successfully used SimpleGestures on other parts of the website but the action only happens at the end of the gesture.  In this case I want the user to be able to select an item and drag the whole list up and down interactively.

Any ideas how to do this?

Thanks in advance,

Nico
