Using CodeIgniter to interface with vbulletin database?

Of course it is. All the data is in MySQL, the sessions are in $_SESSION and the files are on your file system.

There might be a few general PHP classes you can make into a CI library either third-party or rip them right out of vB.

Remember to post anything you make back up here for all to enjoy!
