Depending on your OS, you'll probably have to install gdal-ecw and copy
the ecw dll (that you must acquire, or have on your system) in the osgeo
directory. Search the net for detailed updated instructions.

I think the best is to ask them to distribute it (they are using QGIS,
so they have already solved this). It would be nice to ask them to put
these instructions on their public website.
However, I think tehy also distribute data and services in "normal" CRS.
All the best.
