It is possible to do this, but you would have to write some C code that
you can call into from Ruby that would basically execute the string
passed in as a parameter to a method call.  We have some code like this
that we use to test the encoders included in the framework.  The thing
to keep in mind here is that you would only be able to execute shellcode
that is native to the operating system that you're running Ruby on.  For
instance, if you're using Metasploit on Windows, you'd only be able to
run the Windows shellcode.
