portage knows where to download the files from, and you have told it
where the best mirrors are for you, why second guess it!

How about this:

Get a list of the packages you want to update from the target machine.
something like:

emerge -uDp world|grep ebuild|awk '{print($4)}'>packlist

take packlist to the connected machine and type:

for package in `cat packlist` ; do DISTDIR=/where/ever/i/want emerge
--nodeps -f =$package; done

The files will then be in /where/ever/i/want and you can put them on a
cd or whatever method you are using and take them away.

--nodeps will make sure that your connected host doesn't substitute its
own idea of what the deps are (perhaps based on different USE flags)


You could also probably do something like:

for package in `cat packlist` ; do DISTDIR="/where/ever/i/want" GENTOO_MIRRORS="local
/usr/portage/distfiles" emerge --nodeps -f =$package; done

The GENTOO_MIRRORS="local /usr/portage/distfiles" should take files from
the local system in preference to downloading them, which will save your
bandwidth, although i am not 100% sure of the syntax. 

In other words let your network connected host choose where to download
from.
