Multi-tenancy in Postgres

I've just read through a paper here: http://www.edbt.org/Proceedings/2011-Uppsala/papers/edbt/a12-schiller.pdf about multi-tenancy.

They used Postgres for their work and while it is academic and would need further work I'm just wondering if anyone in the Postgres team is looking at implementing some of the functionality described?

Thank you
