Hi, i read that you need some models, I'm no artist and am a bit skeptic
about you being dependant on qt and kde, but I recommend you to take a
look in http://virtualworlds.wikia.com/wiki/3d_models_list a wiki for
free game media, please be careful when choosing models, I recommend
strongly against the use of CreativeCommons-NonCommercial licenses, as
they are very agains the GPL spirit, there are nice gpl models too in
the wiki though.
By the way, I'm active in a wiki about Free games, I have a special
interest in authors, so maybe you can tell me about the team member's
homepages/ohloh.net accounts or something.
PS: What is the license of the content in Boson? And another thing I
remember: about a half year ago I built boson (which was quite
troublesome) it might be good for you to provide binaries (I'm on linux)
