Yes this is possible. Just like it's possible for Bitcoin developers to force a special block into the network to give them a billion coins. Doesn't mean either will happen. All the Bitcoin developers need to do is ensure Deepbit (trust node 1) , btcguild (trust node2) and mtgox accept the change. Not much difference between our networks from that perspective.
A lie.
Falsehood #1:
"ensure Deepbit (trust node 1) , btcguild (trust node2)"
Truth:
Deepbit + btcguild don't have 51% of hashing power and as p2pool grows hopefully soon the top 3 pools will be <51%.
Difference with ScamCoin:
You don't need support of anyone. Getting 2 or 3 major pools plus largest exchange to do along with a scam that personally affects them also is a stretch. You convincing yourself is a little easier (as evident by your numerous protocol changes which have only benefited you).
Falsehood #2:
"and mtgox accept the change"
Truth:
Even if 51% of miners agree on a change it will be a fork of the network. The real (non billion btc block) Bitcoin will continue to exist. The developers and their co-conspirators can't prevent existing Bitcoin from operating and likely the new "false" Bitcoin won't have any real support. MtGox (and major pools) would suffer massively and their only compensation would be nearly worthless alt-bitcoins. MtGox isn't essential for Bitcoin but Bitcoin is essential for MtGox.
Differences with ScamCoin:
Not only can you alter ScamCoin by royal decree you can also ensure the original fork dies off (via use of enforcer nodes). This ensures users have absolutely no choice but to accept your changes. Not doing so causes any ScamCoin holdings to "vanish".
2) They can be also be transferred to the "CPF" which has no limits on spending.
No if you read the source code you will see theres a limit on how much can be transferred, and that's only 5% of a user block, per trust block. So we're talking millions of years at current rates before they would be transferred. They also are unusable in that manner once they drop under 1 million (trust node threshold), so the total amount possible to be given to CPF is 200K * 10 or 2 million, and at current rates that would take thousands of years.
I could flick a switch and do anything I wanted with the source code
Exactly.
just like the Bitcoin developers could.
Except they can't.
I have no reason to do so though as it would hurt SolidCoin
The whole implicit trust thing. I don't need to trust the developers of Bitcoin to do the "right thing" because it is outside their control. ScamCoin is absolutely controlled by you and you have done numerous things so hurt it. Someone can negatively affect something through intent/malice ("I am going to hack this system") or through disprortionate gain ("I am going to sell off my online game to some hearless company like Sony") or through ignorance ("hey let me make the coinz go up by cutting reward 80%. Didn't work? lets try 99.9%"). Even if you were driven to not intentionally damage the value of ScamCoin you can (and have) still damage it by ignorance and greed.
If you don't trust me or the other SolidCoin developers, stay away from SolidCoin.
The only useful and honest thing you have said in last month or so.
