This tutorial shows how to deploy a web2py app on the Google appengine. Please notice that: 1) this is experimental stuff; 2) the google appengine query language is very limited and it only supports a subset of the ORM functionality normally supported by web2py with SQLite,MySQL,PostgreSQL and Oracle; 3) sessions, tickets, cache, file upload and administrative interface will not run on the appengine because it does not allow write on the filesystem.
