I've read descriptions of VarioConnect, but not EcoVario and Refreshabraille.
Nor was Baum's Web site much help. Just for the curious, what is distinctive
about the latter two?

I may be wrong, but I don't recall seeing support for the VarioPro series,
which I only know from descriptions on the Baum Web site - I'm not in a
position to access hardware in order to help with development, unfortunately.
