Assembling a reliable and fast pub/sub network on top of IPFS

[JGAntunes]

Allow for the propagation of information in a structured manner using a pub sub pattern. The challenges could possibly be, how to route information across peers without putting too much pressure on the network (either way pub->sub, sub->pub) while giving basic guarantees like basic reliability and fast enough to be used in a real world scenario. Might be interesting to pursue the notion of "authenticated streams" mentioned here.
