Application Server

I have a customer that wants to run NW5.0 as an application server. He wants to run 3 Foxpro programs from the server, the Eudora client for 10 pc’s from the server, and he wants to have the word and excel files run the server also. He thinks thatit will work. What I need is some something I can show him that it’s not designed to work that way. Can someone point me in the right direction????????
