Thanks! Yes, you could basically select from various downloadable ‘audio experiences’/layers for that area… The localized user-contribution based audio wiki/encyclopedia type-thing is an interesting idea... Even people telling stories or guiding people around an area… I did think about how users might be able to upload content to a location for others (like an audio grafitti-ish type thing), but I imagine the moderation/networking/storage part of it would be tricky to get right…
