Only the HOST of the meeting can offer that option.
The HOST has to go into Adobe Conenct Central and access their room. On Connect Central they go to the recordings tab under the room and select the recording. Once selected they can choose "Make Public" and then "Make Offline". At that stage they will see Connect Add-In launch and the meeting will play completely from start to end. It has to record that "playback" locally so the PC/Mac cannot be used for anything else while that is going on. Once completed the FLV file is located on the local PC/Mac. That FLV file can be posted anywhere for others to download. You could use the File Share POD in a public room to share the file for people to download.
