Intercom (Voice chat) system with multiple (12) computers.

I need a voice conference program that will accept a max of simultaneous 15 users at a time (max). There needs to be 2 different programs. A client program and a host program. The host can broadcast to all the users, but the client can only communicate directly to the host. Also, text chat between users is required. It doesn't have to be anything fancy, just simple text messaging. The chat will only be used on a LAN, meaning that the IP addresses are [login to view URL], and the IP addresses are static. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. The program must contain 2 separate EXE's. EXE #1) Host program. This is the program that all the client programs will connect to. This program will be able to broadcast live voice messages to any of the client computers that are connected to it. EXE #2) Client program. This is the program that will connect to the host. The client can send voice messages to the host, but not between each other. Text messaging is also required between the clients, and the host. If the program could be programmed in Visual Basic, that would be great, but anything will do. ## Platform The program must run on Windows 98/ME and Windows XP Pro. ****************************************************** ****************************************************** Thanks for the replies guys, I'll start replying to each of you soon once I get some time. ## Deadline information Only bids from people who know what they are doing, and don't charge an outrageous amount. The budget for this program isn't a lot.
