As Tim said, this hasn't changed yet - for admin installs it goes into
the system directory.

For 2.3 releases it will stay this way, for future releases I
don't know.

win32all is growing in a direction where it makes fewer use of the
registry than in the past, and the sandbox py2exe is already able to
create frozen com servers which work fine with python23.dll in the
executable directory, so I assume somewhere in the future Python
releases don't need dlls in the system directory anymore.
