Hi, Just saw this post now. I'm the developer of the wms/mapserver/postgis/wfs interface AppForMap and the next version uses ajax. You can see a preliminary demo here:
http://demo.mapuse.net/ajax/client_classic.phtml It uses ajax to all map functions including editing of features. There is still some bugs in this demo version and it is not released yet but is available form cvs at mapuse.net /martin
