I think it sounds really great BUT.
I would advise you all run this by your lawyers if you have not already. The fact that revenue will be made off these listings may cause a liability on the end of Jelsoft for the content of those listings. Although I would personally never hold anyone here responsible for any damage caused by an outside vendor found in your listings, this world has people in it that would.

Nothing wrong with playing it safe.
Who would of thought someone would need to be warned that Mcdonald's coffee is served hot..... :ermm:
With that said I cant wait to see this implemented. I know there has to be some mods out there I dont know about that I could use.
Thanks!
