Is it open-souce? If yes, where I can get the source?
Is it "playable"? If yes, where I can play it?
Where I can get more info about it?
unfortunately we never took it past the techdemo stage. Jadestone (my previous employer) still sit on the source, but i doubt it would be useful to anyone (many things hacked together like techdemo prototypes tend to be).
Using the hang glider in the old demo is still fun though s
To be honest I was looking forward to get those models, not the code. It's possible to see that there's no much code done, but those kind of models with nice animations are soooooooo hard to find.
I think that I'll need to hire a 3D guy 
Well there was a nice-looking gui, some high-end spell effects, shiny water, decent models. What jME needs to ascend is a big game made by it. If noone does it, we will:)
yeah you better do that 
i don't think using 3-4 models with a walk/run animation and a very specific texture from someone elses techdemo will do that much good for your own game s

See the Resource Links page on the jME wiki for free models, textures, tools, etc.
