launch an exe from inside another exe

[Shub-Nigurrath]

well,
this is a request for comments not on how to include an exe as a resource inside another win32 exe/dll, but rather on how to execute it from memory without a dump on disk. I perfectly know how to handle resources, embed, extract and so on, but the problem is the way I want to launch the hidden exe, without disk dumps..

For the dlls there's the solution I also documented here (http://www.accessroot.com/arteam/site/download.php?view.103), using which you can launch a dll directly from the memory. But what happens for the exe files? I would need something similar to CreateProcessfromMemory().
Is there something similar around? I mean something ready, not implying modifications on my code (which would take time I don't have).

thanks!
