After long weeks of work, just published a dev version of my twitter bootstrap modal module: https://drupal.org/project/twitter_bootstrap_modal
The modal loads any Drupal URL link signed by a specific class inside a Drupal Modal.
It only takes the content part of the URL, without loading any extra region. It has also an option to personalize the output via a view mode for nodes.
So far it is working OK on production sites, loading content, forms and scripts, but has not been tested over complex environments as views involving ajax for an example.
It relies on the https://drupal.org/project/jquery_ajax_load module for AJAX callbacks.
We are seriously commited on Bootstrap/Drupal integration and hope we find a growing community.
