Why not just mount the ring on the inside [small] ring location? (You will need track or BMX chainring bolts, or some spacers to take up the extra threads on the road chainring bolts (Sheldon sells them)).
That provides a good chainline with 120 / horizontal drops. Some people find re-dishing the rear wheel desirable, but not always. It is often preferable to respace the rear hub slightly. This moves the single cog closer to the right dropout, providing a better chainline. This definitely necessitates a re-dish. It's not always necessary, and depends on what track cog, hub, and BB axle you use, as well as whether you have a thick or thin cup BB, and how worn the crank arms are (as to how far they go onto the BB axle).
I have this setup on my fixie with 165 Strada arms. 120 early 70's spacing. I even have a 70mm Italian BB. It was fine even stock, but of course I am in the process of respacing and re-dishing, because I can, and because I want it perfect.
See Sheldon's site on the fixie topic. Lots of good info there.

Here's a lurker type question. If the inside chainring lips of a mid '70s Campy strada (144 bcd) crankarm were removed, would it have the same dimensions as an equivalent pista crankarm? i.e. could you use a pista bb and get appropriate alignment with a 120mm fixed rear hub mounted on a '70s era road bike with Campagnolo horizontal dropouts?
