What does this mean?<br /> <br /> basically all virtual worlds are client server<br /> - server may be distributed, but all are controlled by the same entity<br /> - so, who has the power? the server. All of it<br /> <br /> So, peer-to-peer virtual worlds have to share power, somehow<br /> - my stuff is my stuff?<br /> - my power is &quot;equal&quot; to that of others?<br /> <br /> Closest to this is custom servers<br /> - i.e., run your own minecraft server<br /> - person running the server has absolute power but can<br /> grant powers to arbitrary players<br /> <br /> A truly peer-to-peer world means that everyone is running their own<br /> custom servers<br /> - peer to peer!<br /> - client is the server<br /> - connect worlds to worlds<br /> - we can walk from one world to another<br /> - but it depends on the peer-to-peer relationships<br /> - social graph is reflected in the physical graph<br /> <br /> The most interesting part of ccr was its approach to code<br /> - normally, the developer of the client &amp; server determine everything<br /> - but with ccr, &quot;players&quot; should control how their worlds work<br /> - code was mobile, to a degree<br /> - to make anything work, you need code<br /> - code is also fundamentally dangerous<br /> - you would limit the &quot;physics&quot; of the world to limit the abilities of code<br /> - more than sandboxing<br /> - recognition that communication is fundamentally dangerous<br /> - so you better limit it at the lowest level<br /> <br /> one problem of ccr was it was really slow<br /> - shouldn&#039;t be so much of an issue now<br /> - but maybe it would be because ccr was designed to be slow (simulating<br /> &quot;physics&quot;<br /> &lt;/pre&gt;</div>
