I don’t know if what I ask for is a programming nightmare or not, but I have developed many Smart Notebook files for music classes that make use of attached sound files to objects. This is SUCH an amazing feature of Notebook and opens all kinds of design doors. I can make a screen-based piano or a matching objects game to match pitches. And much more.
When I used my new Smartboard I was thrilled to figure out that I could download those original Notebook files to the Player on the board and they worked! BUT, not so with converting them to SLSO files for students to use on their own devices... If there is any way that this could be done, the music teacher (and language teachers) of the world would forever be in your debt!
