Hi Mister Blue,

You ask a great question.
Here are some of the things I would like to see in a future virtual world viewer:

#1 - Open source -- goes without saying

#2 - Multi-platform -- it should run on the Web, standalone, and tablets. JavaScript maybe? Or something that compiles to it.

#3 - VR-enabled -- it should be ready to run on the Oculus and other VR displays and inputs

#4 - Modular with a small core -- the core viewer should be as simple as possible, possibly just a non-interactive *viewer* without avatars, and all features (such as avatars, chat, build, etc) should be added as plugable, optional moduleswith corresponding server-side support. In fact, the viewer-side modules should be downloaded from the server-side as people visit the server (a la JavaScript on the Web) -- that's the maximum flexibility, as it allows for all kinds of additional features and differentiation. Voice chat is an important feature for many, but should also be optional.

#5 - Modern graphics -- I don't really know what this entails, but it would be nice to have environments and avatars like those in Call of Duty. This may be at odds with #2.

I'm not sure if this requires a whole new server side or if we can use OpenSim for a while. People have added WebSockets support, and that's ripe for being improved.

If you start this project, I hope I have time to help! I would like that very much.

I've been seriously thinking about creating a new viewer project. But with Maria's survey[1] and all the different virtual world announcements happening and the lively OpenSimulator vs Unity discussion on the opensim-user list, I'd like to open up the discussion to the OpenSimulator development community[2].

LL is making a new world and viewer (closed and proprietary as far as I know). HighFidelity is making a new world and viewer (open source with commercial 'grid services'). Unity 5 will have a multi-platform web viewer and a new multi-user backend (pricing not announced). There are various wonderful open source virtual world projects (realXtend, Virtual World Framework, ...) as well as many emerging technologies (xml3d, html5, asm.js). There are several forks of OpenSimulator (Aurora, ArribaSim, ...) that have made many enhancements to the base system. Add to that several successful virtual worlds build on OpenSimulator (inWorldz, Anvination, Kitely, ...) as well as a few packaged distributions of OpenSimulator (Diva, ...). Add to that the many SL/OpenSim third party viewers based on the LL viewer. And that's just in our sphere. There is much more happening in the gaming and education and training communities.

So, what could a new viewer add to the mix? Whatever a new view does, it approaches the question of what OpenSimulator should be three years from now.

For me, there are two basic choices[3]: evolutionary change or revolutionary change.

Evolutionary change says to build on existing OpenSimulator. Make due with the existing LLLP (Linden Lab Legacy Protocol) and improve vehicles, make installation and use easier and add an easier to use and improve viewer.

Revolutionary change would be striking off on a new virtual world architecture. It could have LLLP support but only for downward compatibility and to keep that community and content. But other questions arise: How would one build a viewer/virtual world where a HiFi avatar could stand next to a SL avatar? How could content be delivered to a viewer so it is displayable but is not in the original, copyable form? How to leverage the distribution and power of 'the cloud'[4]? How could one make hypergridable grids across the many virtual worlds?

What do you  think? Evolution or revolution?
