The most direct way would be to go to Python at sourceforge[1] and make 
a feature request to add peek to itertools.  (This is probably the most 
reasonable location for it.)  Requests accompanied by patches are much 
more likely to be accepted. =)  Of course, your feature, if accepted, 
wouldn't be applied until Python 2.5, which is probably about a year and 
a half off.

I actually thought about doing this myself, but I've got a few other 
things on my stack, and since itertools is (I believe) written in C, 
writing the patch would be a little more work...

Help yourself.  That's what the Cookbook's for. =)
