Nice Way of Building Links

I'm in the process of sponsoring a WordPress template. WordPress is a blog publishing system similiar to Blogger, and the template being the skin or front end that the publisher and users see. By sponsoring a template, a link to my website gets embedded in the footer of the template. The hope is that thousands of bloggers will download and use this template, and I will in turn get thousands of backlinks. The backlinks most likely won't be relevent, but some could pass a little PageRank as frequently updated websites (or blogs) are given high PR. Just a tip - make sure the template you are sponsoring has the footer encrypted so your link can't be removed!
