I think it sounds reasonable so far, I do have a couple of questions though.
It was mentioned before that a static IP is required. I guess this is because an address needs to be provided so it can be added to the config file.
Is it possible instead to have a domain name that tracks a dynamic IP? Or must it be static?
Also, someone mentioned that DDOS protection would be required as the nodes would be targetted. Is this just an assumption or has this been proven to be the case from other coins that have masternodes set up?
What is the real risk in hosting a node on a server used for other perposes?
