How hard would it be to create a Drupal module so I can get it to be integrated with Drupal?
Just to add...I can't do it myself if it is easy, I am not smart enough. But if it could be a consideration - that would be great. The Drupal core forum is horrible...advanced forums is not much better. There is a petition for Drupal to upgrade forums. There is a Vanilla integration module because of this demand. I am sure the Drupal community would be interested in better forum option.
I would be happy to see an integration module for popular CMS as well. WordPress, Joomla and Drupal.
Even though I spent a little time with Drupal, TBH I'm not sure what would imply create a module for it...
Since you are asking I guess you are somehow familiar with it? Do you have handy some links to tutorials on creating modules? O:-)

Of course, you would probably want to create a module for Drupal 8.x instead of 7.
I use 7 still, so I am just being selfish.
