And there will be at least three people that don't want it to be generic (as a bunch of tar-zipped files), but intuitive to install via a one-click installer and with shiny icon etc.
That means one cannot generically target "Linux" (which is a kernel used in tiny things, mobiles, etc., servers, big clouds), but one has at least to decide for a package format or one specific reference desktop operating system.
As an example, Valve also lists only one reference (linux based) operating system. This serves already the vast majority of the market, but they are open enough to allow from-scratchers to adopt the package to there system of choice, via various wiki instructions.
Just recently Valve has started to promote of all things Blender in their developer tools market. Not sure what their plans are. On the other side, SketchUp has managed to survive with strong competitors next door, even without being perfect.
