I'm bookmarking that. Meanwhile, I've investigated Wildspark, and I'm in. Too late for the beta at the start of this month, apparently :/

In particular, the posts at the Synereo blog are lucid and compelling.

Is there any way you can arrange a beta invite? :) Pick a private channel and I'll give you my email, and sign anything you want against my PGP key: https://steemit.com/pgp/@earthbound/my-public-pgp-key

I can imagine success for AMP and STEEM.
