Hi, I was looking at the ticket mentioned below, are the tests from GEOES 
mentioned by Chris Schmit committed somewhere (I can't seem to find them in 
the tests dir) ? I worked on JTS on similar things a while back and as I need 
this functionality for one of my ongoing projects, I actually might be of 
help, just need to get in focus where things are. I did not check on 
OpenLayers in quite some time but it seemed a good fit for a task so I 
checked out the latest stuff and was surprised how much it has progressed in 
the last year and a half.
