It'd be great if StreetPass could let other player's trainers/teams appear in your game as opponents, like back during the Third Gen with Secret Bases (also, if Secret Bases returned)...
I'm thinking more like Gen 2 and the Viridian City Trainer House. Put them in one spot. I don't want to run around looking for trainers to battle that I may never find. And I'd hope I'd get experience from the Trainer Battles too. :) --- Donnel is my # 1 bro.

I think one of the leaks said you can design your clothes slightly, perhaps (if that's true) you could share designs with other people.
Other than that, perhaps leaving a Pokemon up for trade with certain parameters for what you want in return, and then if you streetpass someone with a Pokemon up that meets your criteria you instantly trade... Sort of a StreetPass GTS. --- 3DS FC: 1332-8189-4231
I think it'd be great if it did a complete "mix records" thing like in RSE. You get their secret base, where you can battle them (how about we allow trades, too?) and they appear on your TV and whatever, too.
I'd also like to see something where you can play with their Pokemon in Pokemon Amie, or have their Pokemon play with yours (think of Nintendogs multiplayer)
It would be cool if it did all kinds of thigns... --- "Earth is a silly place. Half the world has no clean water. And the other half has so much, they poo in it." 3DS FC: 2750 1911 5515
