Hi linux users.
I just installed the demo and managed to export the “Control Animation” sample to HTML5. 
Exporting to video breaks (see log entry at bottom of post) and further experimentation is still required. 
But, the main goal of “does it work” is achieved.
I just double-clicked the exe file in the Dolphin file manager to start the WINE process, it downloaded mono, and all installed without error.
