Morten, I work as a developer for a company that develop both ArcIMS and AGS applications for clients and the reason I asked this question was that I wanted to know the plans for customize-able OOB applications in AGS10. There has been some rumours about it for a while and I think that clients would like to see this feature so that they can build their own apps.
You answered my question by saying "We might include something like this down the road, but for now.."
and I am happy with that answer 🙂
I totally agree with you regarding develop small targeted apps rather than a ArcMap in the browser and that seems to be what our clients want as well..
