LanTalk.NET office instant messenger for LAN, WAN or Internet (without server)

LanTalk.NET Enterprise instant messenger for business networks. No setup, no administrator, no server. The program does everything on its own. It does not require a server. Instead, the program uses TCP/IP and UDC protocols, and port 2307 (by default), to make sure that there aren t any problems with a firewall. All PCs "communicate" to each other directly. The application automatically determines which users are available on its own. Thus, there is no need to set up or administer the program. Second, the program works with any network - Intranet, Internet, LAN, WAN, and VPN. It really makes a lot of sense. Instant messaging communication inside one office is great, but what if you need to discuss something with a person in another branch, located thousands of miles away and not connected to your network? Or what if one of your key employees is away on business or vacation, but wants so stay in touch? The number of people who telecomute makes this feature very important. Instant messaging software should work inside and outside the office. With LanTalk.NET, any person can be included. Connection via Internet works for both static and dynamic IPs ( dynamic IPs allowed for an one side only ).
