Ankron, i think i made the compression...
Code:

class Huffman
{
static $HuffmanTable = array(array(0x02, 0x00), array(0x05, 0x1F), array(0x06, 0x22), array(0x07, 0x34), array(0x07, 0x75), array(0x06, 0x28), array(0x06, 0x3B), array(0x07, 0x32), array(0x08, 0xE0),

Just need to send a string of chr() to the function, and it will return a string of chr() compressed
With this, you can run the server from any PHP 5.3> installation (linux, mac and even windows).
