Sampsa,

The problem is that statically compiled programs (other than code that  
runs directly on the hardware, like firmware code) are not just a blob  
on binary instructions.  They are wrapped in complicated linker  
formats (ELF, Mach-O, PE, etc.) containing metadata, dynamic linker  
instructions, and lots of other stuff.  Hence the problem is a lot  
more complicated than just dumping out, say, the hex output of the JIT.
