Building uberApps

The documentation discusses building uberApps from a development system. Can these uberApps also be built on the host running uberXMHF?

Moving post to top-level.

Can these uberApps also be built on the host running uberXMHF?

Although not a typical use case, yes, there is nothing preventing building the uberApps on a host running uberXMHF. However, the documentation assumes you are on a seperate development box, so you may need to adjust/tweak the build packages/installation paths accordingly.
