OK, my first question: how does one store points in ECEF coordinates? Specifically, how does one indicate in the header that the points are in ECEF? liblas::SpatialReference seems to only talk about the usual geographic and projected CRSes. In our case, the data is gathered and processed in ECEF, served as ECEF, and rendered on the client in ECEF. It would be sad to have to convert from ECEF to something like lat-lon or UTM, in order to write LAS, then have to convert back again on read.
If there is no explicit support in LAS or libLAS for ECEF, i suppose i could just write ECEF anyway, which would no doubt work for reading our own files - but then interoperability is lost.
