No, not really. In release 3 of the ICP you can hotswap 2 like devices with each other in that the extensions swap locations. It is not the same hotdesking as the 3300 where the signed in location moves and supresses the other extension.
Both methods have their own advantages, free(200) and flexibility(3300).
One other thing cool about the hotswap is that it will also work with dnic sets as long as you swap like devices (4025 to 4025, etc)
