I know I'm a bit slow, I am really interested in what you are doing here from the perspective of being able to ink annotate over the ide - we have several failed attempts at getting this going how we would like it to. We were so frustrated with the extensiblity
(or not) of ides we published a paper on it. It should be in ACM DL by now, but if not it is here http://www.cs.auckland.ac.nz/~beryl/publications/CHINZ_2008_Issues_of_Extending_IDES.pdf
love to hear if you think it will be achievable with the new version.
