Has anyone been involved with an implementation of QC interfaced to a customer support app?

We are looking at doing an interface to QC where QC would handle defect tracking and resolution and another app would be the CRM. The CRM app would handle logging customer issues, tracking of customers, products licensed and all other customer facing stuff. Once the customer issue is logged it would be interfaced (loaded) by an undefined process into QC for resolution.

I really like the functionality of QC and it seems like the tool would interface pretty easily but wonder if there are comments or warnings I should know about. [img]/images/graemlins/confused.gif[/img]
