VastPark is reportedly going to use the NICTA p2p technology.
If this sounds familiar that might be because the defunct Outback Online virtual world was supposedly using the NICTA P2P technology.
I personally would be a bit leary of a website with “eccentro” in it’s name associated with a virtual world than never reached pre-alpha.
Eccentro’s site says
” We have developed highly scalable, robust and efficient technology for creation and deployment of large-scale virtual worlds that are persistent, collaborative, interconnected and interactive. We have designed network architecture that can support unlimited number of users in a virtual world.
Using this technology, virtual world developers can create large-scale virtual worlds that are interlinked to form a virtual world web.
Our technology utilises a peer-to-peer network for spatially indexing the virtual world thereby providing unlimited scalabilty. “
