This is a natural outgrowth of the success of the net. The Internet model is being applied to the Internet itself to explore new ways to expand the net. This keeps everything evolving away from centralized solutions which the net has successfully challenged over the years. Expanding on this theme... Imagine that you have several networks scattered around the world. Imagine that they run some strange protocol called IPv8 that is very similar to IPv4 and requires minimal changes to FreeBSD to support. see <http://comm.unety.net/US/IL/Naperville/Unir>; for IPv8 info Imagine that IPv8 supports 2,048 different 32 bit address spaces and that the goal is to tunnel between all of these networks in an efficient manner to provide global connectivity for an OuterInternet that supports many more sources and destinations than the current Internet. Imagine that you decide to use the Legacy Internet as purely a transport vehicle between large IPv8 islands or Galaxies. Imagine that the challenge is to build a FreeBSD based system that can act as a gateway (or StarGate) for these Galaxies and provide inter-Galaxy communication. With a substantial increase in available "IP addresses", imagine that you could easily obtain your own permanent /16 (formerly Class B) address to allocate to friends, families, clients, customers, dogs, cats, etc. as you see fit. These would be allocated to people that help with the system and express a need and interest. Imagine that there are 8 Galaxies and 256 Stargates per Galaxy (8x256=2,048) Imagine that someone is willing to donate 8 fully loaded $8,000 FreeBSD-based Pentium systems to be located around the world for testing this network. Imagine that FreeBSD users could use these systems not only for testing various tunneling strategies but also as FTP servers, mirror sites and other purposes. The $64,000 question is... Is the FreeBSD community cohesive enough to build an OuterInternet to not only support its current development but also to explore the advantages of re-inventing the net by using the Internet as a transport for a semi-private FreeBSD net? I would be curious if people think this has merit, is doable, is a worthwhile project, would be interesting to students, would help the FreeBSD effort, etc. I would also be curious whether people would be willing to host a StarGate and where people think these StarGates should be placed in the Galaxies. I am also curious how people would propose that these StarGates interchange routing information and utilize the ip-in-ip tunneling which is where we came in... ...beyond this I am curious about people's ideas about distributed object technology that can be transported on the FreeBSD network...we will save that for later...if and when the net starts to grow out of the FreeBSD efforts... -- Jim Fleming UNETY Systems, Inc.
