So maybe i am wrong, because i didn't saw this news anywhere, but i was watching Nintendo Treehouse event and they just said it is possible to do that.
So, all you need is 1 Triforce card and 3 3DS. While you use the card, your friends will get the "download play" on eShop (for free i understand) and you 3 will be able to play ALL levels. And that's it, very awesome if true (huge for me actually).
Here is the link, at 3:08 he is talking about that. https://www.youtube.com/watch?v=lXFeuxiL1F0
