GlenW: I'd like to add in to that list the German Physiks: The DDD is a real point source omni driver. Further - it is the only single-element point source omni driver I know of that's commercially available.
One of the coolest models they have is the Unicorn - a Carbon Fiber DDD mounted atop a specially designed bass horn that can deliver all frequencies from below 40Hz through 24kHz from a single, omni point source.
(Disclaimer: I distribute German Physiks in the USA. Still - they are unreasonably wonderful loudspeakers no matter how you slice it).
