Namespaces can also be generalized by unifying under the DAL:
dal = DAL()
dal.define_namespace('app',request.application)
dal.define_namespace('shared','_shared')
dal.shared.define_database('gaedb','google')
dal.app.define_database('gaedb','google')
dal.shared.gaedb.define_table('posts',dal.Field('title'))
db = dal.shared.gaedb
db.posts._tablename -> '_shared__posts'
