-Python in a Sandbox
+description:
+
+In the 17 years of Python existence there have been numerous
+approaches to "sandbox" Python, Zope's RestrictedPython
+and Google AppEngine being popular examples. PyPy takes
+a fresh approach and allows to systematically control
+all access to Files and IO. This not only allows
+to prevent a process from accessing system resources
+but it allows to provide a fully virtualized system environment -
+for example a Python program cannot easily detect that its
+file objects are in fact provided by another Python process.
+
+Not only Files and IO but also RAM and CPU usage are controlable
+which makes the PyPy approach probably the first to
+provide a fully sandboxed Python environment without placing
+restrictions on language usage.
+
+We'll also discuss discuss some open issues and will take
+further discussion - probably schedule Open Space time
+to discuss further work.
+
+Note that in this talk we will not talk much about
+architecture and other aspects of the PyPy projects.
