There's an article in this week's Science magazine indicating that the definition of length may become based on time in a new standard expected to be adopted this fall. The meter would be defined as the length of the path traveled by light in a vacuum during a time interval of 1/299,792,458 of a second. Thus the speed of light would be defined to be 299,792,458 meters per second and as measurement techniques result in more accurate measures of the speed of light the length of the meter would change, not the definition of the speed of light.
