Abstract
Analogue models of gravity have been a test field for many phenomena in quantum field theory on curved spacetimes.  It was recently recognized that in some situations they can also provide toy models of emergent gravity.  We shall review here such a model and address within it the nature and scale of the cosmological constrant trying to draw general lessons for emergent gravity scenarios.
