-- Copying my response to the JTL thread in the Developer forums --
We are aware of some servers that claim to have JTL, but we're not aware of any that have the pre-CU game, fully functioning. That said some have used stolen source code to get the NGE experience going, we refuse to use the stolen code, we prefer to keep with our original direction of developing code from scratch.
Yes, but collision is not working well so you can't fight or fly to places without just running through everything.
Spaceships are houses, so navigating the interiors is not a big challenge.
You can see them on the mini-map, and to some extent outside the windows, but again without collision its not a great experience.
Yes it is possible.
Many more things are possible with extra developer support, again this isn't use throwing our hands up, we've spent many months digging in and found the challenges to be more than we can address in a timely manner.
Thanks for the questions and recognizing that we're doing our best to keep the game alive.
