either you add redundantly groups or you have to resort to a recursive
query each time you need to check for membership at higher levels than the
first one... in either case I really don't see the issue: given that
auth_membership is a one-to-many, web2py isn't getting in your way.
If you don't want to go for the multiple membership way, you can code
easily a function that given the lowest membership checks recursively for
higher levels in your own
city-->state-->country-->world-->galaxy-->universe-->whatever map.
