I think the community should whip up some guidelines for dingux applications.
Like DinguXMB requires, applications should have either .sh (shell script) or .dge (executable) extensions. Outside of that, roms and other standalone files (music/movies/etc) should best be located outside of the /local dir. That way, /local should be more confined to being for the Dinux operating system.
Not sure how all Dinux-applications would deal with files outside /local though, architecture-wise.
