Four Key Disagreements Between Bitcoin Classic and Bitcoin ...

Could Bitcoin adopt InstantX?

Somebody made a comment about zero-conf transactions in Bitcoin in Bitcoin, and (as Bitcoiners seem relatively uninformed about Dash technology) I replied explaining InstantX:
It seems to be a matter of philosophy, whether Bitcoin is cash or a settlement layer. Zero-conf transactions aren't needed in a settlement layer.
Dash has an elegant solution to this called InstantX. An InstantX transaction is sent with a command to lock the inputs being spent. After the transaction is propagated, a subset of masternodes is selected to determine if there was consensus (ie no double spend attempt). Once consensus is formed, the masternodes broadcast a message to say that the transaction is valid. The transaction still needs to be confirmed in a block, as normal, but clients can accept the transaction with 0 confirmations with a high degree of confidence that it can't be double spent. In the event of a problem, the transactions fall back to normal block confirmation.
It seems to me this could largely be adapted for use in Bitcoin, the only difference being that as Bitcoin nodes don't require any collateral payment, Sybil attacks are easier to pull off. But it may still be possible to port this across. However the biggest barrier is not the technology, but the fact that Core is set on implementing a settlement layer, and 0-conf can never work in an artificially space-constrained blockchain.
I read the paper Transaction Locking and Masternode Consensus: A Mechanism for Mitigating Double Spending Attacks, and this explains that any transaction locking technique to prevent double spends must mitigate against:
I can see that for some things masternodes and their required collateral are essential. For example, governance voting would not work without masternodes, because it would be trivial to Sybil attack: you could easily spin up thousands of nodes to bias a vote in favour of your proposal, which you would only have to maintain while the vote is going through. In fact, this is what we've seen with Bitcoin Core vs Classic: some people have spun up hundreds of notes to demonstrate their support for their side of the fence, and at some point in the future, those nodes will die off. I am not saying that is wrong, but it is a much weaker demonstration of commitment than holding collateral. To put it short, "proof of stake" beats "proof of temporary Amazon EC2 budget".
But I am wondering, in the case of InstantX, how much advantage do masternodes give? You need a large proportion of nodes to Sybil attack InstantX. And in the case where all Bitcoin nodes are dropping double spend transactions, blocks are not full, and nobody is implementing the deceptively-named Replace By Fee, zero-conf transactions have been shown to be relatively safe.
So where is the advantage Dash has with masternodes, in this case? (I am not doubting that it has one, I just don't fully understand it yet. Also, please correct me if anything in my description of InstantX was wrong!)

Any websites out there that do anything like this?

Remember the bitcoin elevator talk? We need the same thing regarding Core vs Classic.

We need a simple narrative that explains to core users what is going on. We need to be able to defuse the attacks and show our points in a non-threatening manner.
Any ideas?

Fragility of Bitcoin under Classic vs Core vs Unlimited vs XT

Planning for an attack on the network is always something bitcoiners should be strategizing and prioritizing. The bitcoin network is a social network of code producers, miners, investors, users. The individual and interactions among these elements determine the ultimate design of bitcoin, or the progression of bitcoin code and thus bitcoin's role in society. What blocksize scheme will lead to the least fragility of the network against attacks?
sorts of attacks: 51%, flooding (ddos), sybil, others
