To the OP: As a guy who is writing a fantasy book (which would probably be better suited for a webcomic, if it were not for my lack of a scanner and time for drawing the comic) about an eccentric loner living in an airship (and his personality is basically the same as mine), I support your idea. Please, post it here when you have made enough pages to make it readable.

Sorry for this terrible joke, by the way.
