PHP活泼互动，在多个网站聊天和跟踪用户的访问

The main description will fit in some kind of live chat support system. However, there are some big differences and advantages: You can open a chat window (inline or pop-up) to any online visitor. Run on multiple sites: one master centralized site and many clients (domains) to serve. Optimized for high traffic sites. Client sites just need add a small javascript, no php involved. Only open connections when some status change (admin logged, new chat, etc). Chat"s script is really fast using filesystem for writing. Idem for reading, just show file contents via ajax. Show your online status. Log chat messages.
