Implement paging in media rss feeds

I looked into PicLens Views module source and I see that it calls views_build_view() function with pager limit = 0.This means that if there're 10000 nodes returned by the view, then rss would contain all 10000 nodes. I guess would be a performance killer. I saw a description on PicLens site about paging implementation: http://www.piclens.com/lite/webmasterguide.php#pagination, I guess this would be a good feature to implement.
