[wp-hackers] Feed Hooks?

index.php?author_name=bill&category_name=games&feed=rss2
index.php?search=hello+world&feed=rss2

Any query can be turned into a feed by adding feed=xxx where xxx is rss,
rss2, atom, etc.  What we don't currently do is allow multiple authors,
categories, etc. to be specified.  If someone want's to try their hand at
adding support for array syntax to wp-blog-header and WP_Query, that would
be cool.

Ex: &category_name[]=rss&category_name[]=games&category_name[]=wordpress
