Informix OLWS 7.22 on NT licensing schema ... Delphi ...

Hi, I'm new on Delphi and hope some of you can help me. We are in the process of evaluating different options to develop business applications to fulfill different requirements. One of the options we are evaluating is the following: - Windows NT 4.0 server box (running TCP/IP). - Informix On-Line WorkGroup Server 7.22 for NT. - Delphi to develop client applications that will use the Informix DB. The questions are: 1) How many NT licenses will i need ?. (I will use the NT box just for the Informix database, i will not use any print or file facility from NT). Do I need an NT client license for each client workstation running the Delphi application or not ?. 2) Same question for Informix Database server. How many Informix client licenses do I need to buy ? One per each client running the appl. ? 3) Any difference if Delphi C/S 2 is used instead of 3.0 ? 4) Anyone already using this scenario ? Recommendations ? Suggestions ? Thanks in advance, Manel.
