Hi Riccardo,

 From what I could tell, there is no way to toggle the readOnly option 
dynamically after the annotator has been loaded.

However, I did accomplish the method of reloading annotations (for 
another use case) by executing the Store._onLoadAnnotationsMethod 
(https://github.com/berkmancenter/h2o/blob/master/public/javascripts/h2o-annotator.js#L696) 
upon a certain onclick.

Also, of note, I was able to loop through the annotations and 
temporarily remove annotations 
(https://github.com/berkmancenter/h2o/blob/master/public/javascripts/collages_annotatorv2.js#L254-260 
and 
https://github.com/berkmancenter/h2o/blob/master/public/javascripts/h2o-annotator.js#L699-721).

My use case for this functionality is a bit different from what you 
intend to do, but it does contain the basics of loading additional 
annotations and deleting annotations on the fly.
