M$SQL Emulation

Hi, I am currently needing to build a server app in REBOL probably using Rugby. The trick is that it must, for all intents & purposes, look exactly like M$SQL Server 2000 to the app that calls it. What I am trying to acomplish is database access from the web using a program written created in Borland C++ Builder 5 using ADO Components. I am not certain this is even possible, but if I could do this it would be excellent. Any ideas, anyone? Thanks!! Ammon
