Edit: Psychopathic Clown is being very nice and making a pair of ships. You can find the Mod discussion
here.
I would like to see a large spaceship, capable of supporting a full crew. Hopefully there would be a piliot, steering the thing, a few gunners, and possibly an engineer. It would be really cool if the engineer could direct power flow to weps/thruster/shields but I don't know if that's possible. Heck, I don't think the shields are possible.
Why is this a good idea? Well with the rebirth of the planets map, a couple of servers have popped up. It's really hard to do a space rp with inter-planar travel without a decent ship that can hold more than one player. At the moment, all that comes to mind was the star trek ship made a while ago, but it's kind of... well yeah.
A space to store fighters would be very cool as well, though may be too difficult to accomplish. /nomount script, as in carrier, perhaps?
Anyways, here are some ideas for ships:

Battlestar Pegasus

Star Destroyer
