Delphi C/S operating on OS/2 Warp

I have a potential client (a $20b U.S. bank) who is a deeply committed
OS/2 shop. Users have OS/2 Warp workstations  and they are running an
OS/2 LAN.

I have a 16 bit Delphi C/S app which I want to work on an Oracle 8
database.

What sort of problems can I expect

        Applications running smoothly

        Connectivity to host / server

        Potential of running an NT Server

        Othe surprises
