Great stuff! I'll take a look at this asap (meant to when you sent
your first mail but was still wrestling with the hg-git plugin which
requires an update of my mercurial install)

BTW existing annotater "application" is now available as a mercurial
repo here: <https://knowledgeforge.net/okfn/annotater/>

I'll have a play around in FF on ubuntu and see if anything breaks.

One last thing: I've been thinking that we may want to allow for
different types of reference. For example, when doing shakespeare
often users just want to record a line number or even just a scene
reference. That said I don't think this should affect the *javascript*
since any given reference format can be transformed by the backend
into the required css selectors ...
