Provide examples of multi-sig scripts

What are the possible Bitcoin scripts to create a multi-sig transaction? Please provide the script code with explanations.

I would like to see at least two types of such scripts explained (OP_CHECKMULTISIG and the one with conditional OP_IF statements that Steve Shadders showed at this CoinGeek Seoul presentation). If there are more options, please list them as well.

To Bitcoin or not

Bitcoin is all good and well and I am also invested in it. My question is what will happen when governments take control of Bitcoin? Look what happened way back on April 5, 1933 when Roosevelt declared all privately owned gold illegal. Will this happen again? If so, then is Bitcoin the alternative?

What is Miner ID, how it works and what can it be used for?

There has been a lot of discussion going on about Miner ID lately. What is Miner ID and how does it work? Is it optional for miners to use and what would be their incentive for or against it?

Which cool new possibilities does it enable?

What will replace OP_CHECKLOCKTIMEVERIFY & OP_CHECKSEQUENCEVERIFY after the Genesis upgrade?

Since these two opcodes will be removed after Genesis and (from my understanding) nLockTime works in a slightly different way (prevents transaction from being included in a block vs. UTXO being locked until given time/block height), how will be possible to achieve same functionality after that?

Is it possible to build a locking/redeem script using other opcodes that achieves the same result? Or is there something else?
