If your AerWave account has access to multiple domains, you'll have the ability to copy Programs (and other assets) between them.  To do this, just access the Programs tab, then click the copy button on the right (two sheets of paper icon).  You'll be given a prompt to copy that Program to any or all domains you have access to.


This action creates a copy of the Program on a different domain, however it does not copy the assets contained in the Program.  It just references the assets on the original domain.  This means that any change you make to the original Playlist will take affect on the players on the other domain.  If you modified the content files (ie replaced them), this would also take affect everywhere.  However, changes within the Program itself (content placement on the timeline, duration etc) will not affect copies.
