Hi Bob,
If you want to demo of S&OP on HANA, you can reserve one of the S&OP demo systems (If you are SAP internal), or most of our Partners have a Partner system which they use to demo S&OP and also do Custom Demos.
Other option is the 3 Day S&OP trail available on Marketplace. http://scn.sap.com/community/scm/sop/blog/2013/08/22/sap-sales-and-operations-planning--free-trial-now-available
You can use this to demonstrate the functionality of S&OP on HANA solution.
Hope this helps.
Thanks,
Raghav
