You normally query annotations from a source, so you have the provenance 
there. The URIs are just segmenting the primary data:

<http://www.w3.org/DesignIssues/LinkedData.html#offset_717_729>
      a str:StringInContext ;
      wa:comment <http://myannotation.org/comment/kf094erk430943k> ;
      wa:comment <http://myannotation.org/comment/3089joifdjlkdsfsffj> .

No problem, obviously, but you would need blank nodes or UUIDs.

as likely as two md5 hashes colliding in the wild ;)
I think, we might change the syntax a little, so it looks like a mixture 
of MediaFragments and rfc5147
http://www.w3.org/DesignIssues/LinkedData.html#char=717,729&x=y

What are the chances that somebody uses:
<h2 id="offset_717_729" >title</h2>
<h2 id="char=717,729&x=y" >title</h2>

We are working on incorporating xPointer and HTML as well, especially 
for ITS 2.0.
