But that still does not dismiss its purpose and right now ELF is in full swing and when the time comes... 10, 20, 30 years down the road then you simply add something else but by that point 32 bit computing will probably be history so there wont need to be any of this fuss for ELF or 32 bit support at that time. -- jhell
