Check out the RESTful web services 
functionality: 
http://web2py.com/books/default/chapter/29/10#Restful-Web-Services, 
in 
particular, 
http://web2py.com/books/default/chapter/29/10#parse_as_rest-(experimental).

You could also handle this specific case in a controller action, with all 
the elements of your URL in request.args:

In default.py:

def TopThing():
    rows = db((db.TopThing.id == db.MiddleThing.TopThing_id) &
              (db.MiddleThing.id == db.BottomThing.MiddleThing_id) &
              (db.TopThing.id == request.args(0)) &
              (db.MiddleThing.id = request.args(2))).select()
    return dict(rows=rows)
