FYI, we have a portlet cache implementation on CPSPortlets tied with the
CPS event service for the cache invalidation :

If you wanna check :
http://svn.nuxeo.org/trac/pub/file/CPSPortlets/trunk/doc/cpsportlets-RAMCache-draft.txt

And the implementation over there :
http://svn.nuxeo.org/trac/pub/file/CPSPortlets/trunk/PortletRAMCache.py

And the ESI support on the portlet there :
http://svn.nuxeo.org/trac/pub/file/CPSPortlets/trunk/CPSPortlet.py

We never tested it though in here ;) Maybe Jean-Marc ?

Feel free to ask questions on the cps lists if you feel like...

Cheers,

	J.
