Hi Anthony and Peter, I have posted the .pps file of the presentation on the EDUCAUSE site (http://www.educause.edu/WRC08/Program/14068?PRODUCT_CODE=WRC08/SESS18)
The file is kind of big (1.3MB), so I don't think I could upload it here. I will see if I could find some time to use Camtasia to do a voice-over over these slides but at the same time if you have any specific questions about the slides, please feel free to email me (whchuang at gmail dot com). Thanks!
Hope this helps,
