Audio/IP recognition software

I would like to create a program that will be able to recognize a persons IP address, given from a list that is imported to the program, and automatically play a personalized welcome messege that I have recorded. For example, Hello Frank, I am glad that you are visiting my site today........ This is just a bare bones of what I would like to have done. I am looking to have something created that will make the visitor feel welcome, and not just a recording of Welcome Friend...... The only thing that I am not sure of is how can I put each persons name into the program. If there are 100,000 names on my list, will I have record each name separately? As I said I want this to be a personalized greeting with my voice, not a computer's. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site). ## Platform I want the program to be able to run on all version of Windows and be Mac compatible. Also, I want it to run on all versions of Internet explorer and Netscape. This program will be running on a Windows server.
