Integrating wordpress into Drupal 7 site

So I had one plugin for Wordpress which I really wanted to use on one of my Drupal website. Naive approach was:

Nice, SEO-friendly URLs in Catalyst application

I really enjoy power behind Clean URLs in Drupal CMS. It allows me instead of "http://www.example.com/node/123" path to have nice URL like "http://www.example.com/blog/nice-seo-friendly-urls-in-catalyst-application". And most important I can change this nice url to whatever I want or need.

I found it is quite easy to implement something similar for Catalyst application.
