Spent some time today whipping up a Docker (http://docker.io) image for Koha for a talk I'm going to be giving about Docker later this year. If anybody on-list would like to see how it stands up, you can pull it from Docker's index with docker pull jbfink/koha . 

Note that I am by no means a Koha expert and this is my first time messing with Koha since... oh... 2002 or so, so there may be things with my Koha install which are broken or boneheaded in some way.
