Didn't Palm end up with BeOS?

As a previous poster said there are solutions for this already, such as Vertex Inc [vertexinc.com] and Taxware [adp.com] Companys all over the world have to deal with local tax authorities. How do you think companies like Walmart or McDonald's handle this, do you think they have their local managers tracking tax code? No they have an application that plugs directly into there ERP application which is connected with all their branches and mikely connected directly to their POS system to insure the proper taxes are being charged.
