The suggestion I made off-thread was to have a repetitive starfield --
a 3x3 grid of the same pattern. That way you can invisibly loop the
scrolling of the pattern when you get far enough from the center --
since it's repetitive, there's no way to tell, say, the position (-10,
0) from the position (0, 0) (if each "cell" in the grid were 10x10).
Make the base pattern large enough (2x screen resolution should do)
and the repetition should be hard to notice.

Real-life parallax would be very hard to notice on these scales, but
scrolling starfields are a time-honored tradition for space games. :)
