Hi AJ,
That's outstanding. I am glad to see that there is actually somebody who has made some progress.

> "miners as service providers."
Great idea! Block space as a resource is under-analyzed.

> miner/pool's political positions, their consensus ideology, physic= al location (yes some people would like only miners in particular countries= to mine their transactions)

I am not joking when I say that in 3 to 8 years, I want to be able to
verify my transaction through green blocks that are generated locally
by my neighbor through the excess capacity of his solar panels or by
an NGO pool that promotes solar deployment around the equator.

> The main attitude right now is that people would like to 'support&= #39; miners who signal for the features they care about.

Yes, just selecting all SegWit signaling hash power instead of picking
individual Authorities would be helpful on preferredmin= er.com

> I strongly believe, whether the Bitcoin developer community facilitate= s it or not, certain miners will become preferred by users.

Absolutely, considering the recent language used in opinions by the
ECB and drafts by the EU I see them assembling the artillery. I
wouldn't be surprised if they start target practice next year. That
will mean that commercial interest must have a way to transact on
somewhat regulated space.

> 1) By creating 'segregated mempools' where an authenticated th= ird-party like my web service Preferred Miner manages the access to pending= transactions destined for a specific set of miners

I would call it regulated block space or regulated consensus space. I
hope that we can do that on a deeper level, as part of the p2p
protocol layer.

> 2) by creating transactions where the mining fee is in one way or anot= her, an output to an address owned by the preferred miner(s).

That's a distinct function, e.g. at least some communities charge a tax= . [1]
I fear it is more likely that a business, say Coinbase, will approach
a "miner" and just say "we pay 100 USD for a KB to your bank= account,
here are our transactions with no fee". It will literally be an
off-chain fee. That's what I mean by "secondary market". This= would be
one of the least appealing scenarios.

> There are some terrible pitfalls with both of these methods. [...]

Spot on, that's why this should receive some attention before it
becomes urgent. I think there is much more to it that we are missing
at the moment, e.g. Tom: "Using xthin/compact blocks miners only send<= br class=3D"gmail_msg"> a tiny version of a block which then causes the receiving node to
re-create it using the memory pool."
