[support] twitter/ facebook like comment feature

I am looking for a module which can provide twitter/ facebook like comment feature in drupal site. What i need to achieve is when an user enter a comment say "I will be in @drupalconf tomorrow". The text @drupalconf should turn into a link, if a node with similar title exists in the site. I may have to extend this to other CCK textarea fields also in future.

I found glossify [1] modules does something similar to what i need. I am trying to understand and customize this module. I would like to know your suggests on achieving this. I will be happy to contribute the code to drupal community if required.
