Thanks for the info guys. Sockets sound interesting. Will check the out more. I have played with sockets and flash before, but I will read up more. >From what you are saying I gather that 500 people with an open socket to the program is a lot different to 500 people spawning their own process.

Run ab (Apache Benchmark) and find out. Or use valgrind/callgrind to find out. Or use wget to find out.

Any program can be run as a "service" (Un*x: daemon) Writing that program to do something useful and, more so, efficient, is a bit challenging. Here's a sample "talkback service" that just spits out whatever you put in: http://php.net/sockets -- Some people have a "gift" link here. Know what I want?
