Well, I’ve done it. In fact, it was absurdly easy to do. I brought my first Terra aircraft into OpenSim.

The Imprudence viewer exported the biplane model as XML, minus any textures I didn’t actually own (I’m not sure which those would be, since I textured this myself). Then I ran Sim-on-a-Stick, logged in with Imprudence and imported the XML. Over a period of about 30 seconds, I watched Imprudence assemble the plane in pieces — all 248 of them and all textured correctly. Proof of concept: Now I can start migrating my content away from Second Life.
Just to be perfectly clear, I’m not abandoning Second Life. I just think that it’s good to have a lifeboat available if the Titanic goes down.
UPDATE: After playing around with Imprudence in Second Life for a bit, I find that I can export almost nothing, because there’s always at least one part of the model or textures that have someone else as the “creator”, even if that name is my own alt account. What I need is a viewer that ignores the creator tag. Without that, all of my content is stuck in SL.
Very cool! Will you be making these objects available for sale to OpenSim users? Not that my company grid NEEDS an airplane….
But enterprise and education customers need a place to buy legal content for their enterprise and school grids, and there aren’t enough places out there yet.
Though it’s changing! See: http://www.hypergridbusiness.com/2011/04/designers-offer-opensim-goods-on-websites/

Thanks, Maria. I have no coherent plan about what to do with this ability to move objects to OpenSim, but I’ll think about it.
How does one sell items for an OpenSim environment? As XML? I imagine if I create something and sell it once, it could easily be copied and propagated unchecked to all OpenSim grids. So a pricing model would have to be based on a single sale, rather than selling many copies. Well that’s something to think about. :)
I am currently on the InWorlds Grid and physics will be implemented soon.
I would like to talk to you about developing some certain aircraft if possible
Scripted Physical once physics comes and non physical for the time being
Pheonix dreamscape has nailed it pretty close and even in the non physical form would help to stimulate the community.
