Pipes are created in a visual editor (which you can see above), so no programming skills are necessary to access the data-sources and combine them. This visual tool is very similar to a tool called “Visual Composer” from SAP, which you can see here:
Probably no end-user will create those kind of mashups or composed applications, it is still to “technical” to do it, but it makes it much easier for people who are skilled to do so. Therefore a large number of those apps will be available, each one adapted and optimized for it’s single purpose, perhaps combined of other apps, so the end user has a bigger chance to get what he just needs.
