Oh come on man, don't tell me it's free. Tell me what numbers I can go up to before you give me the "phone call" (if that, you could go Google and just shut stuff off without any notification or warning of any kind) telling me I've hit some sort of API limit.

The ambiguity is like that Oracle Linux debacle.

I don't even really care if you intend on living in fantasy-land and never intend on charging for the service (get real), at least give me some idea of what the limitations are.

I like the live demo though, good idea.

I want to use your service but you need to set up some clearly defined boundaries. I'm not some sort of enterprise-wonk trying to hold you to an uptime contract, I'm a startup guy trying to make certain he's not hinging stuff his company uses on something overly uncertain.
