A PoS hybrid to add security (so that not only PoW is moving the network along) would make sense, assuming a relatively low interest rate. I've got no particular preference myself, though I imagine that I'd benefit from PoS as I hold a few ZRCs.

More importantly, would be great to start seeing some details soon on how the transition will happen from Ziftrcoins to GoCoins. If any of the technical parameters will change (such as emission rate for example), an early announcement would be ideal...
