Maybe we should distinguish:

1. Can you do it at all?  Yes, via the struct package and via the bit
   operators.  And, the bit operators support the same idioms we all
   know and love from C.

2. Can it be done "fast enough"?  Maybe.  I wrote a Morse code
   generator based on algorithms from a C program, which generated pcm
   files.  The initial cut was way too slow.  Then I did some caching
   and got it fast enough to use.  Still not C speeds, but fast enough
   for the task.  But if you are doing encryptions (where even C is
   giving way to hardware), then Python is not the answer.
