It’s broken at my end too. Didn’t debug it, but sticking to the 1.2.4 for now.

If you only need to popup a fancy box on any instant lets say a href, it’s piece of cake, depending upon how fancy* is integrated. I worked with a css bases fancybox and this is how it was achieved.
<a href=".." class="fancybox">Text</a>
it’s a baby solution.

If you wanted to control redirection, use wp user control widget.

<div class="fancybox"><?php wp_loginout(); ?></div>
<div class="fancybox"><?php wp_register("",""); ?></div>

I’m throwing you a bone.

Well, it’s very hard to say, I tried and eventually crashed my installation after trying so many things, modding every single file. But this is something we wont be doing. Every single file is calling the instances of wp- prefixes, which IDK seems too foolish. Opensource with a branding sux. Joomla is still a very best and I’ve done a hell lot of modding on that.
Coming back to the topic, you got only one shot, i.e. your apache mod rewrite, study it and you might be able to generate custom url, but don’t expect WP to do anything for you on this ??

I’m trying this code and will update about the resultant code here.
