I didn't really imagine that an acceleration-caused event horizon warps space (particularly since it will, I think, generally be a long way from the accelerating observer?) I wouldn't imagine that acceleration in itself warps space...? But I *do *seem to recall that the accel-caused EH emits Hawking radiation, which is ... interesting, at least.
