I do have concerns about viability of the DarkTor concept.  TOR exit nodes face some challenging liability issues because of the statistical likelihood they will output illegal content at some point (see discussion at https://www.torproject.org/eff/tor-legal-faq).  For that reason many TOR node operators choose to only operate relay nodes. 

If the proposal here is to essentially turn every masternode into a potential TOR exit node (when its turn comes up in some deterministic algorithm), I think that could present new and challenging new legal risks for DRK's masternode operators AND the providers that host them, at least in many jurisdictions.
