An API for storage?

Blogged in Panlibus - Amazon have released a web service storage service.

The blogosphere seems to think it could be game changing.

Does this mean the end of the data centre?

Why fly a new disk pack + air con + UPS + support staff for your new database/archive/registry, when you could pay Amazon $0.15/GB/Month to do it for you?

How many of your eggs would you trust Amazon to put in their basket?

Given cheep web storage, what new toys could we build?

Suggestions........?
