InstantX may going to be our nuclear-weapon, if it gets implemented before dark and we get significant coverage in coindesk and other leading medias.
lol, you don't even have a network (let alone even structure of masternodes) and you're talking about IX. LMFAO.
Darkcoin has even had InstantTX running in testnet. I've sent a few ITXs myself.
Who knows though, maybe Mr Spread has a better way to do it up his sleeve and will beat Darkcoin to it.
I highly doubt it.
SPR nodes are not even in testnet yet.
