MU Domain Mapping – Icons not domain mapping

We are using the WordPress MU Domain Mapping plugin on a production Multisite setup.

Live Example URL: http://www.digitalcameraworld.com/

We have installed and configured Social Media Feather, however the URLs for the icons are not changing to the mapped domains. It would be great to have Multisite support added very soon, as I’m afraid we will have to remove this plugin and look for another solution. The internal network subdomains are intentionally configured to return a 403 when accessed externally, therefore the icons are not showing to our end users.
