How does IP2IP work?

I heard a lot of discussions mentioning IP2IP at the recent CoinGeek conference in Seoul. I really like the idea of users exchanging transactions peer-to-peer, but I am wondering how IP2IP works on a technical level?

Does it require a daemon/service running on the recipient’s computer that listens for incoming transactions or is there some other approach?

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.

If transaction hashes only are stored in blocks, then where is OP_RETURN data stored?

An answer to a previous question and the whitepaper both agree that blocks don’t store full transactions, but rather, transaction hashes.

So then, what if I add data in OP_RETURN, say, the text “Hello, world!” Isn’t that a transaction output, or at least contained in an output, and therefore part of a transaction?

If not, or if so and only transaction hashes, not transactions themselves persist, then how does the OP_RETURN data stay on the blockchain?

Christians - which wife with me in Heaven?

Asking for a friend…….

In Christianity, suppose my wife passes away.
We had always considered ourselves “soul mates” who would be reunited in heaven.

I meet someone else, fall in love, and marry wife number 2. My love for number 2 seems to be just as strong as wife number 1…..I consider her also to be my soul mate?

How is this resolved in Christian heaven? Who will I spend eternity with?
