Thank you for the kind words, although it falls somewhat short of a set-up tutorial. There are some very high quality set-up guides out there though. In this post I hoped to highlight the points of difference this witness brings to the table, and how they can be implemented to help the network scale more efficiently.
The best way to promote any development is to ensure the pull request is made on GitHub and an open dialogue is established there, as well as on Steemchat. Are you sure that is the correct profile? The user does not appear to have any development content.
For now, you can already view a complete witness list here.
Many thanks for your precise and thorough answer - it brings me more confidence in Steem's future fate to see this network may rely on the work and support of that dedicated members like @deltik and yourself (and it makes me hope that someday the Steemit community will be able to convert it to the free software regime).
And yes, the Witness list I was refering to is the one you mentioned (made by @drakos, with an -s at the end :-)).
