What problem are you willing to solve by "handling Maemo trademark to community"? I'm not a legal expert but I guess a trademark needs to be own by a legal entity, being an individual or a constituted organization. As for today "the community" is none of that. You can hint again to the need of creating a legal entity, but still it would be good to know first the problem you want to solve. If maemo.org wants to increase its scope beyond the Maemo OS I don't see why it can't.
