The concept and simplicity make me think of Ghost's (http://ghost.org/features/): free, open source, near-minimalist, and self-hosted.

The seemingly only advantage is that Dropplets doesn't require a database, and its landing page is amazingly beautiful, clear, and to the point (though Ghost's "features" page is slick as well).

On a more technical note, click events seem to be propagated up the player on the landing page, closing it when toggling HD for example.
