Running around inside should definitely be in option... that't what escape pods are all about.
For those of you who played GC (Star Wars mod for 1942) bouncing around inside the falcon or lambda or the giant amphib imperial thing (can't remeber what it's called) was most of the fun of running to the escape pod.
A noob chute you can just shoot out of without moving is no fun. Gotta have the rush...
Running around inside whatever, be they spaceships, sand crawlers, or transports should definitely be in the game.
My two most striking memories from GC are:
a. The sand crawler driving into the sarlaac pit and dumping 15 people out of the open hatch in the front.
and...
b. My first game, bouncing out of the lambda shuttle only to realise the mod had no parachutes.
Adds to the immersion.
