First: yay! hitted on block. +4.36 FCN && 113331 BCN. It works! 

Hm, I think running several deamons (each on one PC) but all using the same outgoing IP address makes no sence?
Maybe this is the reason why only one deamon reports he is allways syncronized and the others not. At least for the Quazarcoin net it's like this for me now.
How can I add more mining PCs in my internal LAN with this solo mining method if I have only one outgoing IP address?
Thx, BitWalker
Run daemon on one pc, then check its ip (you should can do it from routers page ~192.168.1.1 or something like that, or just cmd -> ipconfigall), then it should be as simply as setting this computers ip instead of 127.0.0.1 and normal port as it was. There is possibility you'll need to configure NAT, port triggering or port forwarding, or just configure firewall at host computer.
