3rd Party Feed Authentication

I am looking to add in 3rd party feed authentication so I can grant access to the feed based on a membership plugin.

I think by adding the following line at or about line number 49 I can add in a filter to control the $give_access valuables Boolean condition.

// apply filters for 3rd party integration of membership based feed access
$give_access = apply_filters( 'give_access', $give_access );

What I will likely do is have the members use their wp login info to access the feed.

Is there a better method, is this useful and the proper way to do it and is it worth integrating into the plugin for others to use as well?
