It should also be pointed out that there are application frameworks that 
already implement support for this sort of thing and use OpenLayers as 
the mapping API, such as MapBuilder 
(http://communitymapbuilder.osgeo.org/) and there are a few others.  I 
may be wrong but OpenLayers was originally intended to be an API for 
frameworks like these to use, and it is very good at that.
