Djatoka

In general, djatoka was the easiest option for getting something up and running quick, and it works well with Open Seadragon. It is worth continuing investigating alternatives, though.
IIPImage
Home: http://iipimage.sourceforge.net/
Language: C++
Environment: FCGI server module (needs apache or similar)
Alive: Sort of - last commit february, last release 2009
License: Open source - needs kakadu source code license for JPEG2000 support
Features: Many - tiles, levels, rotate, png/jpg, contrast, brightness, transformations, .....
Discussion
Seems a more finished and robust piece of software than Djatoka, but kakadu source code requirement seems rough.
Harder to get running on JPEG2000 for that reason.
License should be investigated, and tests against djatoka should be made.
Conclusion
We have deployed the Djatoka image server for now, due to its ease of installation.
