Toolan: I think that there are many lessons learned here, but the two most important are that no one wants to foot the bill (on an ongoing basis) of paying a for-profit third party to create, maintain and administer the supply web, and that there is not just one supply-web. The only place where the supply-web concept has worked is when a relatively large customer mandates to its suppliers that it must use the supply web if they want to continue to have a business relationship. Without that type of "do it or else" pressure, suppliers are loathe to take the time and spend the money to connect their systems to B2B systems that simply cut into their profitability. And the fact that there are always a few competing B2B sites simply expands the costs for the suppliers further.
