Yeah working on a new event kind to facilitate this stuff. The goal of the client I'm building is to give fine grained control over what part of an activity you actually share.

Ultimately you'll be able to encrypt the data if you don't want to let others see all of the location data, or choose to not upload it, but allow people to still see stats.

Then utilizing DVMs, you could still get cool aggregates on the stats you choose to make public, like how strava will match a run and give you trends of slower or faster.
