P2P softwares.

I always dream about the power of P2P softwares. It's a kind of software that may hide your real ip and give you the power to communicate/share resources with anonymous people. Apps are connected via networks. Mind/resources are reused via sharing. It looks like a big flea market without paying any money to get something that may surpises you. It's a dream in my mind. I do not know when it may come to real.
