[OpenLayers-Dev] OL-Based GeoEditor

[Dipl. Inf. Carsten Eider]

Hi folks,

i am working on a small geo-editor for an agricultural project in 
rhine-palatinat/germany, visit http://www.agroconnect.de for more 
information.
Upto now my editor has the following features:

    * new polygon, plain OL
    * edit polgon, plain OL
    * delete polygon, plain OL
    * union polygon, OL with a javaserver in the backend

Coming feaures:

    * split polygon into 2 elements, OL with server backend
    * group polygons

At the moment i am hanging a bit with the split-feature.
My idea is

   1. select polygon
   2. select first point/vertix as starting point
   3. select second point as ending point
   4. do split
   5. remove polygon and add the new ones

Step 4 will be done on serverside,but could also be done on clientside.

Any ideas how to realize steps 1-3. Should i use several controls 
(Select and Modify) or
should i subclass Control.ModifyFeature ?

Any hints will be appreciated.
