I know is not possible for me in Indonesia to download the beta version of Flash Media Server 2 (FMS2). But someone on flashcomm mailing list shared about this.

If you install the beta version of Flash Media Server 2 you will found C:\Program Files\Macromedia\Flash Media Server
2\modules\codecs\Screenshare.dll

This mean screen sharing available for FMS2? or just available on beta version which is will expired on November and not on final version.
