Again, you don't even have masternodes setup as a network to provide tx locking. Are you really going to want tx locking on say 50 masternodes? 100? How many is enough to actually provide viable consensus? People keep talking like IX is right around the corner here, maybe it is, but I question sensibility without any pre-existing infrastructure to support its design. Lots of dreamers here, that's for sure.
Why dreamers?
Darkcoin made a powerful masternode network happen in just one year, and this with the quite hefty price tag of 1000 DRK per MN.
SPR masternodes will be more flexible, both in price and in installation requirements.
Plus, the darkcoin people will probably be most interested in running a DRK and SPR masternode side by side... why shouldn't they, if they already have the infrastructure in place?
Sounds like a nice additional profit without any large expenses.
