Yea you just hook the allocator for an interface and have it return a 
proxy object. I have some old directx8 wrapping code that i can strip 
and turn into a demo of this.


Anyway, i added an intro to the site:

"""Hooking represents a useful method of modifying the runtime behavior 
of an application. This is achieved through rerouting API/function calls 
to alternate code locations while still allowing the original code to be 
called from other contexts (ie. from the replacement function). Hooking, 
combined with class wrapping, such as the case with COM objects, can 
completely alter the behavior of the target application without having 
access to its source code.

Executable image parsing allows this to be extended further. Instead of 
globally hooking a procedure we can now modify behavior privately, 
within the context of each DLL or shared object (IAT/PLT:GOT hooking 
method). """


I'm gonna try to get the project setup on dsource.org for SVN / forums. 
  The code and documentation need polishing and whatever feedback is 
appreciated.
