@aeva@mastodon.gamedev.place I've seen a few things about it, partially due to me searching #StreetPass (for the feature inside the Nintendo 3DS, no idea if that inspired the name for this, if so it's super cool)
It's a cool extension by the looks of it, but I don't actually see it being that useful for me personally unfortunate (I'd probably get no hits, just like 3DS StreetPass nowadays I guess lol)
