I have a modified sts oscommerce installation that i need to add FedEx freight and UPSXML to and have the ability to choose which shipping method to use per product. One product might use UPS, another might use FedEx Freight. UPSXML will utulize their dimensional support as well. I had someone working on it that tried to get FedEx Freight + UPSXML + MVS to accomplish this but could not get everything to work together. This has to work correctly and be completed very quickly.
