Recently, RWW posted a very interesting article about the new breed of emerging databases for massively scalable internet applications (http://www.readwriteweb.com/archives/is_the_relational_database_doomed.php). Examples of these kind of databases include Amazon's Dynamo and their newest release called SimpleDB, CouchDB, HyperTable, and of course Google's AppEngine Datastore which is based on Big Table.
In one of the previous Porcupine releases I decided to add the Python's __slots__ class attribute to every class which is schema related. This was done in favor of smaller memory consumption since these classes don't have a dictionary (the __dict__ attribute) for keeping instance variables.
