Forget the data sharing, I've just forked out <$100 for a complete RaspberryPI based ADSB-IN setup which wirelessly shows me traffic on AvPlan. Whatever the merits of the ADSB mandate, I don't see how anyone flying with a tablet-type device can justify not having this functionality at this price.
Both AvPlan and OzRunways support it - see
www.stratux.me or the dedicated OzRunways page (the ozrunways version didn't work for me but I didn't trouble shoot - I just went to the stratux version and it worked out of the box) and away you go.
