  In comparison to the radio and sub-millimetric domains, imaging with optical
interferometry is still in its infancy. Due to the limited number of telescopes
in existing arrays, image generation is a demanding process that relies on
time-consuming reconfiguration of the interferometer array and super-synthesis.
Using single mode optical fibres for the coherent transport of light from the
collecting telescopes to the focal plane, a new generation of interferometers
optimized for imaging can be designed. To support this claim, we report on the
successful completion of the `OHANA Iki project: an end-to-end, on-sky
demonstration of a two-telescope interferometer, built around near-infrared
single mode fibres, carried out as part of the `OHANA project. Having
demonstrated that coherent transport by single-mode fibres is feasible, we
explore the concepts, performances, and limitations of a new imaging facility
with single mode fibres at its heart: Agile Guided Interferometer for
Longbaseline Imaging Synthesis (AGILIS). AGILIS has the potential of becoming a
next generation facility or a precursor to a much larger project like the
Planet Formation Imager (PFI).
