We've been working on this for a while now, and I just released the first beta over at http://www.drupal.org.

Here's a brief rundown:

Features:

* Email integration - Ubercart Ticket can be configured to collect emails from any number of email addresses and creates tickets from the content of the email
* Integration with Ubercart orders - an order pane is created on every order that lists all tickets for that order along with a link to create a new ticket with that order's information
* Integration with the Contact module - Ubercart Ticket adds an 'order picker' to the contact form so that customer can choose which order their question applies to and links that order with the ticket
* Customer information on tickets - Useful customer information is displayed on each ticket. This includes order information, customer contact information, total orders placed, total dollar amount spent, etc.
* Templates - customer service reps can create templates for responses to save time when answering emails

You can download the most recent version at http://www.drupal.org/project/uc_ticket.

Please post any issues you have with the module in the issue queue for the project.

If you have any comments, you can post them here!
