The USGS has really impressed me with their lidar data organization. You can view and download their data in a KML format using any KML viewer. One click on their data markers allows you to download the data in various formats (e.g. DEM, GeoTiff, XYZ, etc.) After playing around with it in Google Earth, I definitely think I will be following their example as a model for my own data organization.

Here is a screen shot of the KML file from Biscayne Bay National Park displayed in Google Earth. The arrows represent areas of lidar data. The yellow dots are SCUBA dive site locations.
