This could get really big.  Are there copies of your data distributed inside the network similar to say, HDFS?  Would it be possible to interact with the network using bash?
 
I have some servers, say I would put a server up with 1 TB, can you give an idea (very rough estimate) how much you would earn per month for opening it up? 0.0001 BTC? 0.01 BTC? 1 BTC?
