Nah, you really mean any azimuthal projection centered on the facets of a
geodesic sphere. IIRC, it has been proposed already, some time ago.
Unfortunately, that means a complete overhaul of the renderers, *plus*
switching openlayers from one projection to another on-the-fly when the user
pans out of the current projection, *plus* a lenghty discussion on whether a
gnomonic or an orthographic or a stereographic or a lambert azimuthal
projection is best.
It'd be cool, but I don't think it's worth the hassle right now.

Sure. Especially complex for you, apparently.
