IronPython *is* a standard Python install.  So is CPython, the one I  
presume you mean.  Even that doesn't offer you any guarantee that it isn't  
going to change what id() returns from one version to the next.  Relying  
on implementation-defined behaviour like this is a good way of getting  
code to blow up in your face.  You'll get much more reliable results by  
starting in a language that was actually intended for direct memory  
access, like C, and wrapping that in Python.
