offline apt-get update?

[Vincent Murphy <murphyv@student.cs.ucc.ie>]

 i have a potato machine which doesn't have access to the outside world
except through a windows machine on the same ethernet segment.  moving the
outside-world-access to the potato machine and proxying for the windows
machine is not an option, and installing wingate on the windows machine
would be a serious dent in my pride.  ;)

 i would like to know how i can manually perform an `apt-get update' on my
machine.  i presume that i need to:

 - download a Packages.gz file for each line in sources.list;
 - `add' said file to apt.

 has anybody done this before?  ideally i would like to get a list of
absolute URLs for the Package.gz files which i can give to wget.  i can do
this for a `apt-get upgrade' by doing

  apt-get -yy --print-uris upgrade | awk '{print $1}'

 any suggestions would be gratefully appreciated.
