With the vsipreload hack [1] from GDAL, you can also use the kakadu demo executables with /vsicurl

Quick recipee (Linux only):

Checkout and build GDAL
cd port/
g++ -fPIC -std=c++11 vsipreload.cpp -shared -o vsipreload.so -lgdal
CPL_CURL_VERBOSE=YES LD_PRELOAD=vsipreload.so kdu_expand -i /vsicurl/http://download.osgeo.org/gdal/data/jpeg2000/utm.jp2 -o out.tif
