Any way to hear audio simultaneously from both Video and StageVideo objects?

In our mobile application that is built using Air, we run simultaneous video feeds.  Video 1 uses the Video object (RTMP FLV Streaming), while video 2 uses the StageVideo object (MP4 Progressive). Since these two objects share the same audio stream and audio mixing is not possible, we can only play the audio from one of these sources – we elect to use the audio from Video 1.  In the perfect world, Air would include mixing capabilities and users would be able to watch both videos and hear both video streams at the same time.

Is this functionally planned for the future, or is there any sort of a workaround to make this possible?

Also, we would like to use two simultaneous StageVideo objects to playback a live H.264 Video stream (.M3U8) as well as a simultaneous MP4, but according to documentation only one StageVideo object may be used at a time which prevents us from doing so. Is there any work around or future plan to make Simultaneous H.264 video playback possible? This is possible to do natively on iOS and Android but we would like to continue to use AIR.
