Hey Erin. Thanks for the note here, and my apologies for the delay in getting you a response – Joyce who posted the thread above initially is unfortunately no longer with us.
We definitely want to incorporate the ability to send events back to Facebook; we don’t have plans for it in the immediate future but it is certainly the end goal. (Building that architecture is unfortunately far more complex than building the export architecture, so we wanted to go ahead and get the FB -> WP approach out there first and foremost.
Hope that helps and sorry I couldn’t offer up more. If you have further questions please do let me know.
