An open source effort for a vendor-neutral exchange format for geo-referenced full waveform LiDAR called PulseWaves. The format is similar to the ASPRS LAS standard, but instead of storing discrete returns, it stores geo-referenced laser pulses and those parts of the outgoing and returning waveforms that were digitized. The source code and the specification of the PulseWaves format have been released under the terms of the LGPL (version 2.1) on github.
