[Opensim-dev] Suggested in-world DNS: .sim

[Kyle]

Very nicely explained Christa.  My own experience with P2P virtual worlds is
very poor.  Latency, offline spaces, lack of structure, no fun at all.

You're making up your own definition of p2p in the context of opensim,  
your definition being "an opensim server and a viewer both running on  
the same box". That's not what p2p is, generally, although one could  
imagine a distribution that would have those as a unit. For "true" p2p  
VWs see OpenCobalt. OpenCobalt is both a server and a browser in the  
same piece of software, one doesn't exist without the other, it's not  
even modeled as server-and-client, it's a unit.

OpenSim is client-server. Even if a client and a server run on the  
same box, the architecture is still client-server. Your friend's  
viewer in his laptop needs to connect to your sim in your laptop in  
order to visit your world; at that point, it's up your opensim server  
to simulate your friend's agent and to serve all simulated data.  
That's where latency plays a role --home DSLs aren't good enough to  
support many clients sucking data from them. Also, your friend's  
opensim server in his latptop plays no role in the simulation of your  
friend's agent in your opensim server -- other than serving identity  
and inventory, in the case of HG, but not simulation.

So, again, not p2p as OpenCobalt. There's an interesting technical  
discussion waiting to happen comparing all these possible  
architectures. But let's start by not confusing things. OpenSim's  
architecture is completely different from OpenCobalt's.
