We got used to this word "Masternodes", but like any "bad" habit we can replace it over time and get used to something different, why not?
There is a rumour out there (not sure if true) that darkcoin/dash is going to trademark all it's features and names, (masternodes, darksend, instantx), and this will make the usage of those terms more restrictive...
But even if that rumour is not true, I strongly advocate that we move away from those fancy darkcoin names and finally find our own identity.
I like generic self-explanatory names like "servernodes" etc because by definition they can't be trademarked and will always stay in public domain, which is a good thing.
F**k trademarks, this doesn't have any place in opensource anyway.
