Stop apt-get downloading same Packages.gz from different mirrors

[Karsten Heymann <karsten.heymann@gmx.de>]

Hi List,

for up-to-date and for bandwith reasons i have multiple debian mirrors
in my sources.list, a close one (which i hope is faster) and the
official master (which i believe is updated first):

deb http://http.us.debian.org/debian testing main contrib non-free
...
deb http://ftp.freenet.de/pub/ftp.debian.org/debian/ testing main  
...

Now if i do 'dselect update' or 'apt-get update' most of the time i see
two 'Packages' files being downloaded, which, if they are what i find in
/var/lib/apt/lists, are equal. Is there any possibility or plan to stop
this double download? (As you can see i'm running woody, but i wouldn't
mind installing some - not too many! - packages from sid).

Maybe reladed:
At the CeBit a debian developer (hi grisu!) talked about a rsync-able
gzip being developed. Is there something new on this?

Yours,

Karsten
