Excuse my ignorance, but what, exactly, can one do with v4 that can't be done with v6? Other than giving people relatively-easily-remembered addresses, that is :P

In other words I could not play properly with the v4 internet.
But that's not anything that v4 can do that v6 can't, inasmuch as it's to do with content availability rather than limitations of v6. All your examples also work perfectly conversely in a v6 world where the odd-one-out is a person with a v4 address - that is, in such a world the v4 person would be SoL for getting much done. I've still not seen a single example of something actually worthwhile that can be done with v4 but not with v6. That applications relying on broadcast addreses in v4 will have to be rewritten is not a "v6 cannot do xyz thing that v4 can" situation, since v6 just does it differently rather than not at all. So, again, what does v4 do that v6 cannot, under any circumstances, do? -- Matthew Poole "Don't use force. Get a bigger hammer."
