You could do the "junk overkill" method. Make a 'junk' or test blogspot blog for pinging and testing out things. Also create a junk wordpress.com blog, youtube account and twitter account for the same purpose. Post your new hyperlink(s) you want indexed on the WP blog, the blogspot, and on a youtube upload in the description. Make a bit.ly shortened link (or the blog post url containing the link) and tweet the bit.ly url;
Wordpress CMS by default is supposed to ping new posts, and Google likewise crawls its properties and social media, so between these 3-4 postings your url has got to get crawled. You could also directly ping the posts on Pingler or Pingomatic etc, for more overkill.
