As GWT-Ext is essentially all in Java, would it be possible to implement some theme/image trickery that loads resources from independant domains?

As per advice in

The image loader class would append different domains (round-robin style) to each image calls to ensure JS code is loading resources from a spread of domains (to get around the 2 downloads per domain browser limit)

A convinence class could be used to allow the developer register the various image domains (which by default would be set to none). Of course the developer would need to ensure they deploy all images to various domains and setup DNS etc.

Any thoughts? Is this possible?
