Hello, I'm looking for a chat server for my website. Requirements: 1. Proved impenetrable security. This is the most important. I can easily code a chat script, but i need something really secure, can't afford to get hacked. 2. Support heavy loads. Like 3.000 connected users simultaneous. 3. Php ajax or flash. Price doesn't matter. All that have to do is to recive/show the messages. But security is the main concern.
