After founding out you can force someone into the undock dock and even fight there (once someone is there you can stay in the dock without too much trouble most of the times). I was thinking: why not add some small litlle station (maybe in s40 or something), that you can dock in... but if you undock you get in a small transparent cube where you can't get out of. (or maybe you can, hell make 2 cubes). In the cube you can have a nice duel, but because the space is so small you'd have to watch out or you'd slam against the wall... of course you could also make it like with the undock thingy, you can get out, but you can't get in (well, sorta). Then the one that gets destroyed or goes out of the cube lose.

What you suggest sounds very easy to do.

in dock || out dock - race tube - out dock || in dock

We should name it THE DOOM CUBE!

or The Spiralling Cylinder of Death!
