Nintendo's WiFi service way too restrictive

However, at the same time I would like to invite anyone I choose a lot more easily than basically swapping IP addresses.

That's a good analogy, actually... this is like PC distance gaming, circa 1994 -- you know, like Doom or Warcraft II (the original version), where either you had to be on a network or know the other person's IP...

Did I mention that I played Warcraft II multiplayer via IP exactly once?

Yeah, it's not exactly the best system, really...
