Is there a way to install the UWA-Modules locally on our groupware-server?

We have an internal RSS-Feed that I would like to make available to our users on the open exchange startpage using the FeedReader-UWA-Module. Now since that feed is only accessible via intranet, I can not pull data by using the "http://www.netvibes.com/modules/feedReader/feedReader.html".

Is there a way to install the php-files locally in our intranet?
