+- remote objects are presented through transparent proxies

+Orthogonal Persistence
+--------------------------
 
+* persist Python objects "invisibly"
 
+* interpose interception of changes to objects
 
-* distribution
+* implement your own custom persistence scheme (e.g. using ZODB)
 
-* stackless
+XXX some demo
 
-* security (taint space)
+Micro threading in PyPy 
+-----------------------
 
-* thunk space
+* stackless *transform* / micro-threads:
 
-* persistance
+* suspending/resuming computations
 
-* JIT (unsure, will be on the previous talk)
+*  pickling/migration of computations

-* disclaimer (not ready for production use, etc)
+* unlimited recursion

+Taint Space 
+--------------------
+
+* control of information data flow:
+   
+  - label sensitive data 
+  - avoid sensitive information leaks
+  - explicit primitive to declassify
+
+* easily implemented as an object space around
+  the standard one securing all operations

+Disclaimer
+----------
+
+* pypy features are not ready for production use

+* although not because they're buggy

+* lack of modules
