Ok, here's the ViewHelper which needed this:

$stylesheet['source'] and $javaScript['source'] contains paths like "resource://SomePackage/foo/bar".

If I see it correctly a similar code is used in the uri.resource ViewHelper but there should be some convenience method in the resource manager/publisher probably don't you think?

Another use-case:
i'm writing a Surf Deployment to push a file from inside a package to the remove node and need a proper way to have a real path to a resource file to use it with a shell command :)

I guess this won't be implemented as API method. We can reconsider after the new resource mgm is merged. It could be a non API public method in the local file system implementation.
