First off, congratulations to System Bliss on the release. It's nice to have options when you're looking for a better way to get your job done.
What's interesting to me is that Atlassian/JIRA has built a viable environment for third party software vendors and open source projects to build on JIRA. That's certainly one of the biggest accomplishments a software vendor can get, as it helps drive sales and renewals of the core product.
