He also conjectures that more LiDAR software will be able to input and output the LAZ format soon. After FME, TopoDOT, GlobalMapper, RiProcess, QT Modeler / QT Reader, ... (see http://laszip.org for a complete list of LAZ-enabled software and LAZ download sites).
The Coastal Services Center, home of the Digital Coast, is one cool place. I visited there in the 1990s while at NOAA-Beaufort and working with the C-CAP program.
