In recent comments @blocktrades made it very clear that this is doable NOW. https://hive.blog/hive-167922/@taskmaster4450/the-decentralizatoin-of-hive-infrastructure

Those with the knowledge and know-how need to make the effort to get pertenent and reliable documentation up ASAP.

(Of course, this wouldn't do any harm to 3Speak either. 😉 )
