Solipsis

One of the most exciting aspects of the huge community that develops shared projects, namely 'open source', is that it does not suffer from the self-restraint or censorship tackling projects as well as tiny improbi, at first sight. Solipsis , for example, is a system for creating virtual worlds, such as the famous MMORPG (Massive Multiplayer Online Role-Playing Game), which, instead of exploiting proprietary technologies and, above all centralized servers, takes a different approach. This Consite in using a structure similar to that of Matching networks (peer-to-peer), eliminating the need for a server and making the design scalable to large sizes. No 'world' comes pre-established, no rules to follow, but everything is entrusted to the inventiveness of users are free to create their own eco-system and integrate it with that of others. If adopted by a sufficient critical mass, this system could open the door to interactions not only unusual, but also to structural changes, impossible with the strict rules of the proprietary code.
