The latest archive of the Air Stream plug-in for Maya includes builds for Maya 2014.
Air Stream works well with the latest version of Maya, but you may need to perform one additional installation step if you wish Air Stream to automatically load when Maya starts:
Create an environment variable named MAYA_PLUG_IN_PATH and assign the full file path to the Air Stream plug-ins directory. If the environment variable already exists, append the Air Stream plug-ins path to the list.
