I'd personally be ok with [something] masternodes. I call them "Spreadcoin masternodes". If you want something catchier than that and Mr. Spread agrees to it, fine. But, "masternode" needs to remain in the name.
Super masternode
Dynamic masternode
Spreadcoin masternode
Stuff like that is fine.
Spreadnode? Nope.
I like dynamic masternode. I hate spreadnode. What is the node spreading? nothing.
I hope that one day we will call it servernode.
At the moment I am ok with decentralized masternode.
