| Sure you will... Both have IAPP, although different forms.
In the 7760, you set up the IP addresses of the other APs that you want to roam with, and they will communicate session information to improve roaming speed. On the 8760, a method that will talk to other 8760s is used without any configuration, and is on by default. 8760's management interfaces will need to be in the same layer 3 subnet to implement IAPP and fast roaming.
Even without IAPP, you can roam to any other access point. It's just a matter of how long it takes to do the roam. For PC data connections, even roaming without IAPP is under 1 second in almost all cases, and you can't even see it in any standard data applications. The only application that you should worry about roaming times is voice applications, when roaming while using encryption. These IAPP methods, and that on the Unified switch are optimized to improve the roams of WPA2 encryption.
Roaming between APs that are not running encryption is quick and easy. The typical issue that network implementers need to overcome is delay in re-authenticating using user/password authentication, and re-keying on a different AP using pre-shared keys.
