  The Laser Guide Star Facility for the VLT will be commissioned during 2003.
This, of course, can only be the first step towards enhancing the scientific
output of the VLT through adaptive optics. So in this contribution we propose
the development of a laser guide star multi-conjugate adaptive optics system.
We consider geometries for the adaptive optics system, and discuss the
technology needed to project up to 5 laser beacons. The rationale for such a
project is provided by an outline of two primary science drivers.
