Apparently during the development of Skycoin, there are hundreds of attacks and FUD campaigns against trying to bring Skycoin down, and recently Synth was held hostage during a robbery (assuming he was telling the truth).
Concerning the Skywire nodes, I currently possess one of the first generation Skywire nodes, which made from several Orangi Pi, but as far as I know, they will develop custom circuit board for the next generation as well as custom antenna with improved range.
If you're still interested in contacting Synth, I can try dropping him a message on Skycoin's telegram.
Btw, in case you are still not aware yet, the guy who made counter arguments on your post about Ouroboros did update his comment after reading yours, and he apologized for being too harsh.
P/S: I'll leave the Skycoin telegram link below, just in case you want to get in touch with Synth: https://t.me/Skycoin ; and Synth's username is @haltingstate
