In case anyone's interested, I've successfully gotten the bridge to associate WordPress nicknames with vB usernames. The condition for this to work is that your WP nicks *must* correspond with their vB nicks.
Just add this to the bridge block in admin/post.php:

PHP Code:

$vb_posterid = $wpdb->get_var("SELECT userid FROM " . $vb_dbprefix . "user WHERE username = '" . $user_nickname . "'"); 


Then proceed to replace all occurrances (in post.php) of $vb_username with $user_nickname and all occurrances of $vb_userid with $vb_posterid. If no userid can be found for the nickname (WP-vB mismatch), the entry in the database will be set at 0 and the postbit will display the user as "Guest" and with "Posts: n/a". Of course, you add this modification at your own risk, the only guarantee you have is that it *works for me*. It is a little hackish (since I use $vb_posterid while i should abolish the $vb_username and $vb_userid in vb3-settings.php and do it all correctly, blah blah), so if anyone feels it should be done prettier, by all means go ahead.
