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?

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.
