Let's play with embeds

https://github.com/dereuromark/MediaEmbed might be a good place to start to provide support for media embeds in comments.

Maybe just use the filters WordPress is using for Embeds?

$vidembed = new WP_Embed();
add_filter( 'comment_text', array( &$vidembed, 'run_shortcode'), 8 );
add_filter( 'comment_text', array( &$vidembed, 'autoembed'), 8 );
add_filter( 'comment_text', 'do_shortcode', 11);

Untested, but theoretically can do oembed and shortcodes.

Perhaps.. that might be a good place to start. The drawback is that the list of providers is short and the primary use would most certainly be images. That leaves just flickr and imgur. With MediaEmbed or oembed-all we could support something as generic as a link to a image hosted anywhere on the web. It would open up a lot of possibilities.

But yes. For 1.1, maybe using the native embed filters would do nicely. Or maybe the native embed filters and we add some sort of generic oEmbed provider for images?
