Telesat is introducing a Low Earth Orbit (LEO) satellite communications system and we are looking at JIRA as a common software/project management tool between Telesat Canada and Telesat Government Solutions (based in Arlington, Virginia) and we need an ITAR-compliant solution as well to remain compliant with U.S. Government security regulations.
Annual premium support subscriptions and having trusted advisers which know how to correctly configure the system before promising a deliverable is just as important as the choice of a platform. If you can expand on the 'killing us' comment, there are a bunch of skilled and smart people in these forums.
