I'm currently using Python 3.0 b3 and I'm curious as to how I can go
about
intercepting things send to print() for some intermediate processing
before
they're actually sent to sys.stdout. Right now I've thought of the
following:

Replace sys.stdout with a class named PrintStream. PrintStream is
defined as
follows:

class PrintStream:
def write( self, message ):
sys.__stdout__. write( '\t{0}'.format( message ) )

Will this work? Basically I want to add a tab character in front of every
message printed. Thanks.

Why don't you try it yourself?
You may replace builtins.print with your own function too. It's not
exactly the same thing, but given your request "intercepti ng things send
to print() before they're sent to sys.stdout" it may be more adequate.
