Account resources are protected and accessible only to the account owner (and I don't think you would want a competitor snooping on your account while you are developing a new application :))
Do you have a use case for this. While I don't think we'll enable any developer to see other developers resources I can see something where a company owns multiple accounts, accessible via a single developer id, and you'll be able to query any of your accounts.
Unfortunately, what you're asking for is pretty insecure - either you'd have to have your account credentials hard-coded into your SWF, or we'd have to allow anyone to scan your account. Either way, there are serious security issues with this kind of thing.
The best way to run this kind of app is to have your own server (which you likely need to serve up a swf anyhow) log in using your account cred, and send data to clients.
