My mate's done it (once on the Westminster circuit, and once on the Tower Bridge/Docklands drag strip). He's about a 1h05 to 1h10 pace rider for a 40km.
I don't see why you couldn't do it on a fixed. I've done most of my timetrials on a fixed, some with tribars some without, anything from 72" to 87", and faster than my geared times.

PS. I'm not volunteering though.
