WordPress/LJ Comments Popup

I’ve searched the forums and it seems no one has figured a way to sync LJ comments with WordPress posts.

So, my workaround is to use LJSync (http://jason.goldsmith.us/wp-plugins/ljsynch.zip) to crosspost entries, and to include a link to my comments from there. The problem is that LJ people don’t seem to want to leave the LJ site to make a comment, so I’d like to find a way to include a link to comments-popup.php and have that open in a small window where people could leave a comment and it would be posted to my WP database. The comments-popup.php file would be written to include other comments people have left either from within my site or within this popup window. My problem is that I can’t figure out how to get the comments-popup.php file to popup from within LJSync’s.

Hopefully this isn’t too confusing. I know what I’m trying to achieve, but I’m not to sure if I’m explaining it the right way. Any help would be appreciated.
