A simple recursive generator should produce what you want while being 
fairly easy to read...

 >>> def permute( choices, length=8 ):
...     if length > 1:
...         for suffix in permute(choices,length-1):
...             for choice in choices:
...                 yield choice + suffix
...     else:
...         for choice in choices:
...             yield choice

That's not the same ordering you wanted, but that's merely a matter of 
swapping the order of choice and suffix.

HTH,
Mike
