"I wonder if there's opportunity for some kind of renaissance of communal living, in one form or another."

Sure and it is happening since a while, take a look here for example:

So far most of the projects are rather in dreamland than in reality, but some are well established and working.

edit: you will also find actual monasterys there if that is your thing
