rss feed and authentication

The following information is required to get an answer:
Get this information from the PHP diagnostic (in the configuration wizard).
Gallery URL (optional but very useful):http://pix.wantit.org
Gallery version:1.4.4-pl6
Apache version:Apache/2.0.53 (FreeBSD) DAV/2 PHP/4.3.10
PHP version (don't just say PHP 4, please):4.3.10

My Gallery is set to hide content from everyone but logged in users. I have RSS enabled.
Is there anyway for the RSS feed to contain the urls of the galleries which are hidden to all but logged in users?

Effectively, I am looking for a way for anonymous users to grab gallery urls via RSS. However, I would want people accessing those urls to be prompted with a login to view any thumbnails or pictures.
