Can anyone tell me why this shouldn't be a set of modules for metasploit? I appreciate the effort put in, the python/ruby argument and that the MIPS_LE shellcode for meterpreter breaks on a lot of boxes, but is there a specific reason why the wheel is being reinvented here instead of putting efforts into extending and improving what's already there?
