Not sure why my attachment didn't make it to the list. Anyway, I've posted Arun's notes on the wiki at http://wiki.apache.org/hadoop/HadoopContributorsMeeting20100506, and included the content of my slide there. (Attachments on the wiki have been disabled - as of today apparently, see SVN commit r775220 - so I wasn't able to post the slide there either.)
