Within the context of local type IIB models arising from branes at
toric Calabi-Yau singularities, a systematic way of joining any
number of desired sectors into a consistent theory is presented. The
different sectors interact via massive messengers with masses
controlled by tunable parameters. A mirror procedure, applied in the
type IIA case, is also discussed, allowing certain intersecting brane
configurations to be joined through massive mediators. Possible
embeddings of the local type IIB models into compact Calabi-Yau
manifolds will also be mentioned.
