The code in 1.6/gdal/frmts/jp2kak/jp2kakdataset.cpp calls upon the  
http://www.kakadusoftware.com/ JPEG2000 software to display, read,  
and write .jp2 files.  This code has not been updated since 2002, and  
does not take advantage of any of the major advances in the Kakadu  
JPEG2000 software, including hardware based acceleration from  
multiple threads.  As a result, the GDAL JP2KAK plug in is 4 to 10  
times slower than the free Kakadu applications available for Linux,  
Mac OS X, Solaris, and Windows.  Professor Taubman, the author of  
Kakadu, has written that a restructuring of the old jp2kakdataset.cpp  
would allow the new, hardware accelerated Kakadu code to be copied  
and pasted in.  I am offering $5,000. for an updated  
jp2kakdataset.cpp delivered no later then 14 Feb 2009.
