You certainly know your market better than I do, but it seems to me that you are taking advantage of a viral effect. As people use Jira (for instance) and they move around from one company to another, they're likely to recommend using Jira at their new places when they get sick of Rational, Remedy, Bugzilla, etc.
People using Jira and realizing that there is a bug tracker that doesn't stink are very likely to bring that message to their next company. The word about a great product spreads... like a virus, albeit a slower moving one than pet rocks.
