I'll give you some explanation - why we decided to use solo minig and won't change our mind.
We're live in student hostel, we don't pay for electricity or internet connection so profitability is improving. I am going to get our first block with current squad and then publicize our success to gain more students in our case - then create large network. It is possible because our campus is really big.

Meanwhile we done some tests. I started bitcoin qt on my computer and cgminer's on my friends computers it all went well. Their got hashes every moment, but I still have some questions.

If a start many cgminer's connected to my bitcoin qt client it will work optimally? Can I adjust efficiency of this connection?

How to check number of connected persons and amount of their Mh/s using bitcoin qt?
