Finally, I will like to set up several master nodes, I lack the technical capability and time to do it myself but will be hiring somebody to do it for me. In that sense I would really appreciate a comprehensive guide on how to set up the master nodes, I think that would be a way better use of the time of the more technically inclined in this forum. Thanks
I'll bet someone will come up with a basic guide and I know the developers are going to try to build safety into this, but do be sure, especially with that much invested, that you cover all security issues possible. Just saying

The only real security issue I can think of is that somebody uses the same password as he uses *everywhere* or doesn't even encrypt the wallet.dat and somebody steals it.
Otherwise, you might get a DDoS attack, but that's just painful, not permanently harmful.
