You should have a look at UPX (upx.sourceforge.net), it does have a
in-place execution feature that seems to be what you are looking for.
Basically it compresses an exe and then sticks a decompression code in
front of it and it allows to decompress and execute the exe in place
without generating files. At least that is what it looks like from
their description. Source is provided, so you can take a look. :)
If you are writing some sort of virus like thing, remember that
signature scans will pick up the decompression or decryption part if
you don't do something about it.
