Rate Limiting: Request on behalf of a user?

[raRaRa]

My use case is to allow people to create real-time slideshow from location and possibly hashtag in the future (if it'll be supported). If I have over 100 active users using Snapchat, then I'd hit the rate limit pretty quickly. Would it be possible to send requests on behalf of the user, by passing his access token via Authorization header. That would be really great.

Thanks.
