Hmm.. it kind of looks like the Debian swirl has been occupied by the dots and lines that make up the Ubuntu circle of friends.

Maybe combine the morse code with the "ae" from the maemo.org logo? I like the fact that where Apple has its lowercase i, KDE has its "K", GNOME has its "G" and MS has its "Direct[...]", "Active[...]", "[...].NET" or "Live [...]" (depending in which year you are in), Maemo now has its "ae" (as can already be seen in app names like "Cinaest").
