You may not have seen this but PayCoin (XPY, not the other one) is going to use the concept of masternodes to secure its network......
How the paycoin network will be managed makes it unique among altcoins today, including peercoin. GAW has sold proprietary wallets in advance of the coin launch, as well as allowed customers to exchange existing mining contracts for the wallets. GAW has said that it will manage these wallets out of its existing data center space.
The network as a whole plans to be supported by a kind of masternode structure similar to the one deployed by darkcoin. GAWs white paper outlines how this infrastructure will help propagate transaction data, and the company itself plans to operate a number of these nodes.

mess scam.
However, it's interesting how far and wide the DRK solutions to crypto issues is propagating, and being used by scammers as a way to bolster their reputation.
