Support for N-Channel image data in Deep Zoom format - think spot colors

[tribalsketch]

We are starting to work on a project to add support for more than 4 color jobs into Deep Zoom format. We would like to be able to process jobs with at least 8 channels - and preferrably 16 channels. This is geared towards the commercial print environment where the need exists for viewing jobs with CMYK plus up to 12 more spot color inks. It seems the new JPEG XR (formerly Windows Media Photo and HD Photo) has the potential to support "N" channel image data. I would love to discuss this project with anyone interested or to start a discussion about how this might be supported in various viewer options. For instance if we were producing JPEG XR now with more than 8 channels would any of the current viewer technologies display it - (Silverlight or HDView)?

Is anyone else working on a similar project? Are there any standards that should be considered for such a project?

Gavin has been doing quite a lot of playing around with Deepzoom. I will drop him a PM
