I’m maintaining an apt repo (using reprepro). Just create a file /etc/apt/sources.list.d/binfalse.list containing the following:

deb http://apt.binfalse.de binfalse main

Packages are signed with my GPG key 8D2DD9BD.

For those as lazy as me:

echo "deb http://apt.binfalse.de binfalse main" > /etc/apt/sources.list.d/binfalse.list
gpg --recv-keys 08E66E72A83A9871CD493441E81BC3078D2DD9BD --keyserver pgp.mit.edu
gpg --export 08E66E72A83A9871CD493441E81BC3078D2DD9BD | apt-key add -
aptitude update

All packages I provide are prefixed with bf-.
