I hope he builds cryptography and maybe better privacy features in the protocol from the ground up this time. If wikileaks proved anything it's that we need a more distributed web, that's probably one of the only things that could guarantee any form of net neutrality.
That is far easier said than done. If the streaming is point to multi-point then the crypto can get tricky, if you allow people to join and leave the group at random it gets tricky, and keeping it all working without providing a list of the participants to each peer is tricky. With BitTorrent Bram started out with a system that had strong crypto and privacy (Mojo Nation) and stripped most of it out because it increased the complexity for little benefit.
Strong crypto and privacy have costs, both in end-user resources and bandwidth implications. Getting it all correct is hard and if you screw up a little it is usually worse than starting from the position that privacy and a secure channel is something that the user has to bring to the table if they really want it.
There doesn't seem to be very much public information about how this protocol actually works. How does it deal with NAT? Will it work on mobile networks? Does it require a native application?
This isn't 100% true. You have unrestricted network access from signed java applets if you request the right permissions (and the user clicks allow), for example.
Also, Bram might have come up with a reliable way around the same-origin-policy. DNS rebinding 2.0?
There are many p2p networks for streaming content - they seem to be popular in Asia for watching English and European football, and I think many of these existed prior to 2007.
I'm sure there's a mountain of other prior art covering the concept. It isn't novel to anybody with half a brain. I was streaming audio in the 90s and clearly remember thinking about a p2p network then, because of the expense and legal threats I was receiving. All I wanted to do was enable football fans living abroad to listen to the local radio station on match days.. I thought I was doing the BBC a favour by extending their broadcast range! Yeah, I was just a naive kid. :)
btw, I hope he doesn't plan on making money on this.
Rinera (now Conviva) tried and failed. Media company executives freak out at any mention of P2P. I bet they freak out even more when they hear P2P and Bram Cohen in the same sentence.
It probably cannot be made to work with flash (without Adobe's help.) To build a p2p system like this, you need greater access to the OS than the flash sandbox will allow. The only way to get this is through a browser plugin.
Octoshape had a special deal with Adobe where the flash player would install the Octoshape plugin, without the user having to do anything. This was because the code was signed by Adobe.
