FYI there's now a branch called physmodules that has this work.We'll have it under testing for some more time, and if no major issues arise, we'll merge it.

Essentially, all new server-side physics should now be provided as a region module (INonSharedRegionModule) that also extends PhysicsScene. See all OpenSim.Region.PhysicsModule.* sub-projects for how to do it. As region modules, the corresponding dlls need the mono addin declarations usually placed in AssemblyInfo.cs.

We had this conversation today in the IRC about the several plugin mechanisms currently being used by assorted parts of OpenSim. A couple of years ago, we made a big push towards the [new] Region Modules mechanism, and that placed about 95% of simulator plugins in that bandwagon. However, a couple of them are still using their own raw "pluginning," and that makes them hard to (1) explain and (2) distribute as 3rd party packages. They were left behind.

One of them is Physics, the other is the client implementations. I would like to propose that we move these last 2 renegades to the Region Module plugin mechanism, so to reduce entropy and to make them easier to package. From our conversation, moving the Physics plugins to region modules is peaceful. I haven't looked at the client dll yet, but I've been told that people experimenting with other client protocols are using region modules anyway.

This affects the MOSES group developing the PhysX plugin, but it should be straightforward to adjust and it has advantages. Once we move the existing physics plugins to this new mechanism, you should be able to do exactly the same to yours -- the changes aren't that big, and it doesn't affect the Physics interface at all; it's just the way of connecting the physics implementation to the interface. Plus it will make it somewhat easier for you to make your physics plugin available for external testers at intermediate (early) times, if you want.

Any objections?
