Work on exporting the data in a clean manner is actively underway on our end. There are actually lots of pieces involved in doing this well, so it's not something we can just throw together quickly. Well, I guess we COULD, but then all the VTTs would be stuck with a quick hack solution, and nobody would be happy. So we're NOT doing it that way.
The mechanism is being designed to support consumption by both user-created tools (e.g. prettified character sheet output) and VTTs. The latter will likely be grabbing the data repeatedly during a session, so we're including support for reporting only deltas. It's a similar mechanism to what we use internally within the product to keep bandwidth utilization to a minimum.
When we have something ready in an early state, I'll be posting to let folks know about it here. I'm certain that @Jamz will want to take a look, and I'm pretty sure a few others will, as well. Then we can assess what adjustments are needed. My best guess is that an early look will likely be a couple weeks from now. Something final really depends on how much tweaking will be needed based on the initial feedback.
