Yes, we know...
It is a brilliant idea. We like Jira and would like to have a publlic Jira in the future so you can see our development progress.
I have been think about this issue all day, but don't have any brilliant solutions yet. The challenge is how tight and the scope of the integration. The base idea would be some kind of connection between an test case and a Jira issue, but how (where should the issue ID be seen) and what more would be needed...
The ideal would be an initial implementation that would cover the base needs.
Let us think about it and study how the Jira Web Service API works.
