Annotorius has been integrated with OpenLayers  to support annotation of maps on zoomable images. Quite excellent work indeed, thanks to Rainer.
As part of IIIF  and Shared Canvas  we have been targeting a similar OpenSeadragon integration with Annotorius and then making this a feature/modality in the Mirador image comparison environment . Part of the roadmap for Mirador is to have annotation viewing and making integrated with OpenSeadragon (or similarly tiled) zooming.
