If you go to the Setlists tab, long press the setlist and tap "Share->Export songs and files", this will generate a .msf file containing the entire setlists. You can then import that file on other devices running MobileSheetsPro and it will create the setlist if needed (or update an existing one), and create/update songs on the device to match what is in the .msf file. This will overwrite any changes that user may have for their version of the matching song, so keep this in mind if users have their own sets of annotations, for example. If you have a more complex scenario like that, then this approach will not work and you'll need to use the library sync feature (which I can describe). 

For users that don't use MobileSheetsPro, select Share->Export files, tap the option to join all of the files into one PDF, and then you can just send them that one PDF to load or print.
