Programmatically posting Facebook comments

My application has obtained publish_stream permissions for a Facebook user.

I'd like to allow the user to post comments for a target URL directly from my mobile application, rather than opening up an embedded browser that then shows the Comment Box plugin. That is, the user doesn't necessarily want to post the link to their feed -- rather they want to participate in any Facebook comment discussion that surrounds that URL.

Naturally, I can read the comments for any URL via the Graph API (eg: a techcrunch article) but I do not know how, or if I can add comments to an arbitrary URL programmatically.

Would love to hear any other suggestions or workarounds开发者_StackOverflow社区 as well. My hope is to piggy back on Facebook comments to allow my users to have a conversation surrounding URLs of interest to them. If at all possible, I'd also prefer to use Facebook, though I can see using Disqus or similar services would be another possibility.
