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

Just throwing this out there to gauge demand...we just created a module (for 98main.com) which processes refunds for Cybersource transactions created through Ubercart. We don't use the Cybersource module for Ubercart because at the time we set up the site I believe SOAP was either not integrated into that module or perhaps it didn't do specifically what we needed.
