Importing from zip files is new in 2.3.  I think it makes it easier to 
install
python on systems with limited resources (think embedded systems,
PDAs, etc)

I am not sure what plat-win is, but I assume it is platform-specific modules
related to running in windows.  Maybe that folder was there in 2.2 because
you had used it for a while and had installed some things in that folder.
It may get created the first time you try to install there...

I guess the import mechanism is smart enough to just skip over those
elements in sys.path that do not exist.
