I wonder how do the bigger ones deal with it -- the ebay, steam and others... Their goal is to provide easy-to-use selling and buying service, might be usefull to read their statements on the problem.
And I really don't understand what exactly is the problem for LFS -- the fact that there is some more monkey work to be done? Or is that you don't actually know how exactly do you deal with it? If latter, it sound really bad and at this moment when people are on hollidays already nothing can be really done properly...
