One more question (I feel like this may be getting a little advanced

):
I managed to run some solo mining with the new version 0.3.23 on a single machine. Then I looked into connecting my secondary machine to it. By adding the line "rpcallowip=10.0.0.*" to my "bitcoin.conf" file, I can connect any computer on my local network to mine solo along with the machine that is running "bitcoin.exe -server".
My questions is: Does this mean that I am effectively mining solo at a hash rate equal to the sum of all the computers connected? Or is this somehow less effective than running one super-powerful local miner?
