Hello Jfeo,
I was looking for the reverse document from the one you shared and found this:
http://www.cisco.com/c/en/us/support/docs/security-vpn/ipsec-negotiation-ike-protocols/46242-lan-to-lan-vpn-client.html
However this example uses an PIX for the spoke site. I will say to use the router config from the document above and the Spoke config from the one below between 2 ASA's.
