Hello cypherpunks; I've been working on a project that I hope will be of interest to some on this list. It has now reached an alpha stage and I could really use some testers. The project is called robonobo. It's a music network built on a networking layer that uses digital cash to achieve fairness and high performance, which translates into reliably being able to stream enough data to be able to play tracks in real time even though the underlying network is p2p. I am using lucre as my underlying digital cash system. This isn't just used as an anti-freeloader measure; nodes constantly auction off their bandwidth, and the network uses a variant of TCP-LP to give more bandwidth to higher bidders, allowing real-time streaming in a p2p environment. The app should work reasonably well, though it is still very much in an alpha state. It is designed to be highly scalable, but some parts of the network are not yet finished and so have unscalable shims holding things together. For this reason it's invite-only at the moment, though the source is fully available should anyone want to poke about at it. The project page is here: http://developer.berlios.de/projects/robonobo and an overview for developers is here: http://openfacts2.berlios.de/wikien/index.php/BerliosProject:Robonobo If anyone is interested in taking a look, please register at http://robonobo.com - alternatively, drop me a line and I'll send you an invite. Please forward this to any individuals or lists you think might be interested. Cheers Will
