Anonymous read with amazon simpledb

Question

I would like to request simpleedb directly from the client using javascript. My application is distinguished by its readability, and I probably do not forward the request through my application server. Is it possible to execute a select query without authentication?

I could set up an authentication server, but it's rather inelegant, because it will just say yes to every read request and present another bottleneck / speedbump / point of failure.

Do other cloud db features (microsoft, google) have this feature?

An authentication server is required, you can use EC2 for this.
