Port to Drupal 6?

First, let me thank you for a great module. I have been using it on my site for quite some time now and works with no issues what so ever.

I'm just wondering if this is going to be ported to Drupal 6. If yes, do you have a time line? I understand things like this take a lot of time and effort. I really hope you will be able to port this module. Best Related link module I've seen.

Thanks again!
