point all your server to the main server with the client, you basically create your own pool
Yes i have 90.000 KHS so that should be 90mh/s right

So i go solo! Is there no way to set up a unix based solo miner? Or is the only way to go to mine directly to ONE windows computer with QT running on it?
90mhash is too good for solo mining

you can run dogeqt client on every pc and run cgminer --scrypt algo. And mine solo on each pc separately.
but how it work, in this way you get lash hashrate?
it is basically the same, you will be using same speed to same network, or setting up a pool will mean the same speed in same network.
