ssh download

ok. so I have a linux machine thousands of miles away that has limited resources and that I use to torrent linux distributions and other legal material from ]LegalTorrents - Film, Music and Digital Media :cool:
what i have been doing is downloading the files then compressing them to a .tgz by logging in with ssh. I then download the files via http, and I must download the files via HTTP.
is there any way I can get it so it tar packages the data only the moment that it is downloaded and stores a small bit of it in ram? so no storage space is waisted.

it could also be just a .tar
