Alien package converter is still an up to date though listed as orphaned Debian package [member=7109]Moltke[/member] which I still use occasionally with a few small more updated RHEL packages. However converting directly from AUR would most likely require starting with converting from Arch to RPM and then converting to Deb or rebuilding source in Debian. There are devs around the web who go to Arch for more cutting edge packages and package them for Deb in specific backports. Anyway the project of an AUR to Deb converter is kinda cool, though with gnome I would note that much is already been done toward universal package management anyway.
