Thanks. I got the same conclusion too. The problem is that you can only use IP address for the "crypto isakmp peer" command. Even though it has the hostname option, the router will automatically convert it to IP address. This defeats the main purpose which is to setup LAN-2-LAN VPN without reference to IP address.
In summary, at this point of time, I don't think it is possible to use hostname for LAN-2-LAN VPN on Cisco router/ASA alone, if preshared key authentication is used.
The alternation option is to use certificate for authentication, or use third party router as the aggressive mode initiator.
