To us we see scalability as the big one.
As fedi scales, it appears that the way media-delivery is centralised, we will just end up with a few big CDN and fedi will be centralised again. In mid-Sept we began talking about an idea we call #'GlutPlug, where entities that toot, boot or fave a media post can become servers of such media. Serving and fetching over I2P would protect the users. An integrity hash set provided by the main server would ensure that provided media is correct.
