Not out of the box, I fear. But you could listen for the
"vertexmodified" / "vertexremoved" events of the vector layer and
programmatically edit the nearby vectors, see here for an example:
http://www.openlayers.org/dev/examples/editing-methods.html

I'd be very interested in the outcome of this approach.

Best regards,
Marc
