[acs-wg] Overview slides for ACS session

[Keisuke Fukui (on the road)]

Folks,

At last I've arrived Athens after the 23 hour travel!
On my way there, I picked the last overview slides and updated some.
Please take a look and feed me back your thought for improvements
or correction.

Thanks in advance!
