Geez, Give a guy some time to work.
I could not remotely get this to work in 5 minutes. Maybe if I had a quadcore machine and a T1 line. Still I was an hour screwing with it.
This is a clever technique that the OP has made a bit more convenient than doing it by hand. It is not a script. It is pasted-in HTML.
I applied the code to a Joomla site that has been live but not yet indexed by Google for the past 10 months. I basically put it together so CJ had a site to look at when I applied to them and then abandoned it.
The amount of strain the code added on the page load crashed my Firefox several times. IE was better but I still had problems. That is my situation and others probably won't experience it. The code is deleted afterward, so load times are only affected while you are doing the technique.
I did verify that the backlinks appeared immediately, however, a link:site search in Google this morning still gave no results. I am not sure how long that might take.
BUT, this site became indexed by Google in about 45 minutes after not being indexed in 10 months.
The link back to your site will be to your domain, not any anchor text. I also counted at least 200 other links in the list; many to unrelated sites, like mine. I'd say they're probably all spam.
I also notice the page where the link appears has a gray Pagerank bar, but the Google server probably has problems because this page is also grayed out.
Clever technique. You'll probably go, 'Doh', when you see it. I don't know the long term value of it and I personally think that the gain in links from one domain is a bit too quick. However it is only 60 with one application.
I only had time to get about 10 in the hour I messed with it.
Definitely gets a site indexed.
