Lots have happened lately which prevented me from finishing the module. I'm having second thoughts now about it: wouldn't be better to make the module create a custom node type, and integrate that into the Drupal nodes? Right now everything is in a custom database.
The scenario would be like this: install the module and create a taxonomy for it to use (or use a more general one) and tell it to. Configure the http engine, user and password, and synchronize between Simpy and your website.
This integration of the bookmarks would mean that you could use other modules to act on the bookmarks (such as rating them, for example).
