You still do not seem to understand the difference between centralized and decentralized cryptocurrencies.
Obviously not, because there is the difference between checkpointing and centralization. NVC and PPC networks are both has no central authority. There is no transactions control.
the simple concept of end-users being able to compile their own client that *disregards* any current checkpoints *should we wish*.
They are able to do anything what they want.
UfaSoft Coin client has no broadcasted checkpointing support, for example. Also there will be an option to disable it in official client, but it still will be enabled by default.
No, I'm obviously not talking about double-spending your own coin.
Double-spend possibility it's the main measure and sign of centralization. If someone has ability to double-spend, then project should be perceived as centralized system. I.e. if there is a pool with more than 51% hashing power in BTC/FC/LTC/whatever, then this systems are centralized. It's quite simple.
Also, PoS 'fully' functional for the past 2 months?
Yes, and it's the main blocks source in the network, for now:

It's my usual gesture IRL, because of my work. I don't trust people, I trust math only. I prefer to be honest in that sense.
