I would say install on one machine, then just copy the C:\Python24 directory, but then you'd have to deal with the missing Registry entries....
That part is pretty trivial to automate as well. Fredrik Lundh has a useful utility on his web site that will do much of what is required. Google for his name and "python registry" to find out more.
