Is it possible to unrestricted some ip in Hotspot? If can, how do we do that 
?
Example: User is able to access to local file server at wire speed while he is limited to internet at 256kbps.
You may disable hotspot limits and create Queues to limit speed of internet connections based on IP of client - it should be the same, if hotspot user is not connected with multiple sessions (if only one session is allowed).
Actually, managing client by IP is what we are doing now but we find it difficult to do so. That why, we are planning to move to hotspot which we can manage by user (much easier).
