Entity Token Filter

This is an input filter allowing the user to embed entity content from anywhere on the site into a textarea. As an example, to create a link to another node somewhere on your site, you could simply say:

<a href="[node:45:url]">[node:45:title]</a>

The beauty of this approach is that this link and title will remain dynamic (dependent on your caching scheme of course), staying up to date now and in the future. This approach is also valid for other types of entities - taxonomy terms, vocabularies, users, comments, files (using the file_entity module). You have full access to any token provided data for these entities, including nested tokens, like:

Check out [node:45:author:name]'s user profile at [node:45:author:url]. 

This module is very much in development, and currently has no access control or user interface to speak of. Try it at your own risk.
