>>  Hi,

>> "The methods the simulator needs" have changed considerably from 0.6.x to
>> pre-0.7. Hence the good advice that many people have voiced that you look
>> into what's coming rather than looking into the past. Looking into what's
>> coming means looking in pre-0.7 code, OpenSim.Services.Interfaces -- those
>> are the interfaces that the simulator needs implemented somewhere. Also look
>> here for info about the services:
>> http://opensimulator.org/wiki/0.7_Planning
>>
>> Another thing that changed was that now the simulator does not impose any
>> particular on-the-wire protocol for accessing the services. Yes, there are
>> reference implementations (OpenSim.Services.Connectors) designed
>> specifically for the ROBUST service implementations, so you may want your
>> service infrastructure to respond to those -- and that would make your
>> infrastructure different from SimianGrid. But you may want to make your
>> infrastructure more immune to changes in OpenSim core reference
>> implementations, rely  on the abstract Interfaces only, and do your own C#
>> connectors. That is exactly what the SimmianGrid infrastructure did/does.
>>
>> Alternatively, you may want to wait until 0.7 comes out, followed by
>> documentation, which would be fine too.

>> [Before projects reach a certain level of maturity and write down their
>> extension "contracts", it's wise for extenders to keep a very close watch
>> over what's going on in core development. The "alpha-ness" of OpenSim at
>> this point is not so much in the instability of the run-time, but in the
>> instability of the extension interfaces. In my view, we're almost reaching
>> the point of maturity that will take us out of alpha, but we're not quite
>> there yet.]
