This is cool, and exactly what I want!
But - do I need this? I am wondering what effect it will have loading up each facebook like/send buttons on the server's CPU resources when multiplied by many stores in a multisite environment and affected by how many items are displayed on each category page view. I'm also using that "products per page" and "sort" code on the category views, and some may view 48/page etc. Unfortunately (as you know) next month I have to start thinning out the calls on the MySQL data to ease up on the RAM ... as it occasionally slows up the server and cause timing out errors.
