As mentioned at cf.Objective(ANZ) yesterday, the ColdFusion 9 EULA has changed to allow for development, testing, and staging servers. See this great thread on Terry Ryan's blog on the subject.
AIR 2 adds support for the detection of storage volume mounting (for example, when your digital camera is plugged in). Kevin Lynch demoed this functionality at MAX last month, and now Christian Cantrell has posted a demonstration that shows how this all works.
