The more I see about the product, the more I like it. There are some significant and extremely valuable tools when looking at integrated secure services from your ArcGIS server and the Geocortex product. It really makes life easier for the GIS users that don't want to think about complicated security models. Especially when you want your users to edit the enterprise data through a highly featured and scaleable web map.
Build it once and use it a bunch. That is our motto.
