Hi Sebastian,

How about establishing an abstract logo, just like Adobe (and many before) did? I think Evince did a good job "mimicking" the curved Adobe Acrobat logo without actually copying it (e.g. by more or less inverting the colour scheme and stylizing Evinces beginning "e"): http://en.wikipedia.org/wiki/Image:Evince_logo.svg
I like that. Something like that with a big F for Freedom might be good :)
Best wishes, Matthias
