Sven,

Well, this is something that could be examined in more detail.  JPEG2000
in NITF *can* work with the ECW based driver.  With the FWTools build
you can set the GDAL_SKIP environment variable to JP2KAK to avoid the
Kakadu driver if you want to see how the ECW SDK based driver works.

Best regards,
