Abstract: A system and related methods facilitating dynamically collaborative electronic commerce over a data network is presented. In this regard, according to one embodiment, an apparatus is presented comprising a collaboration agent, to provide an interface through which digitally disparate sellers, dealers and/or manufacturers agree to selectively participate in commercial transactions for requesting users, and to enable each of the sellers, dealers and/or manufacturers to define terms and conditions under which they selectively participate with one another to facilitate commercial collaboration between these otherwise digitally disparate providers.
