Tiered access to the gateway

[narendasan]

Scoped access (e.g level 0 == everything, level n == public)

@bcongdon How many tiers should there be?

[bcongdon]

Maybe just 2? Not sure what the use case would be for more fine-grained tiers...

[narendasan]

I am thinking public (no token required, token required and a root token)

[bcongdon]

Ah, yeah. Sounds good.
