I've been working on exactly that for a while. I had something going with my FPSC Free Media Browser a while back, but interest was lost in it. So now, I've decided to make it a part of GameXS. There will also hopefully be a tie in with the Molten Byte Design website so that GameXS isn't necessarily needed, but it'll have a search feature, a way to submit new media that is posted, and a categorized view, so that you can sort by segments, entities, sound packs... etc. I'm thinking of dividing that up into genres within those categories. GameXS won't be out for a good couple months, but I can try my hand at the free media browser. I did something smart for once and posted up my source code.
