New Features in Python 1.6

What are the options for users wanting 1.6 that may not have access to
on a regular basis or at all. I'd hate to be disconnected from the net and
find I need that
'one' function that used to be in the standard library ......... e.g. can I
down load the
entire library and forgo the net check ? What happens if there is no net --
will the import function
get unhappy ?
Also when you import like this does the code check the net for a newer
version or only
when you have no version of the particular sub-module ?
