Gear would be listed at a set price which bungie dictates, just like regular vendors. Not just for glimmer, but vanguard marks and motes and other currencies. Seller would only recurve what he would have gotten from dismantling . In the options menu you could list items as "for sale" and by inspecting your character, people could purchase them from your inventory. If bungie didn't want certain things for sale, they could mark them as permanently "not for sale". This would allow both the buying end and the selling end to benefit more than they do now, and keep it pretty fair so your still have to work hard for nice gear. (You'd still have to pay 65 vanguard marks for some legendary gauntlets, and the seller would receive no additional benefit) Read some of the comments and see what you think.
