There is no interface for Ping Plotter to remotely query data - and no way to control it remotely (at least in the current 2.30.1 version).

Beyond that (and getting into slightly less desirable answers), you could set up an alert that auto-emailed you at an interval of your choosing - and this could include a .pp2 data file. The downside of this is that you'd get emails constantly - even when you didn't want them (unless you set up alert conditions to only send you emails when the conditions were bad).
