No, that comment was relating to having clan logos on jerseys - if we had brand name jerseys, I don't think they'd want their logo covered up by some clan logo. And as for using real jersey designs, I'd have to get permission from jt/dye/whoever to use their designs and logos. There's also the problem of GPL compatibility. I want to make everything in the game free under the GPL, which would mean people would have to be able to use the media for whatever they wanted, which would likely conflict with the license of the jt/dye/... logo and/or copyright laws.
But I guess we'd have the same issue with the guns, so...
