by the way, if you want to use socket streaming with php, here's a great php class to deal with : PatServer : http://www.php-tools.de/site.php?&PHPSESSID=522123e243af173b5d84a0873a1e...
it makes operations like data broadcasting and client handling much easier (than the default php socket functions, which have sometimes a weird way of working)
