Here's a backport of deluge/testing for Squeeze: http://wfr.t28.net/deluge-backport/1.3.3-2~bpo60/It's a trivial port that required zero modifications. The directory also contains .debs, built with cowbuilder in a pristine Squeeze environment.
Please review the package and let me know if there's any interest to add it to backports.debian.org.
