That's a good thing...but I noticed that the page you directed me to above was just created a few weeks ago, May 30th, 2016.  My point was while people may well be working on it, most people don't know anything about it - whereas snappy has been getting alot of press.  Granted, it formally was Ubuntu specific - but say what you want about Ubuntu, they do a great job on marketing their brand.  Flatpak may well be superior and "better positioned" - however, unless people start discussing it and marketing it - that won't make a difference and we'll have a situation where the vast majority of applications are packaged for snappy and not Flatpak.  Is that a bad thing?  I don't know - but it is usually the way things end up.  Just an observation.
