<p>
MIX does not standardize an access control model for creating and deleting MIX channels. The choice is left to the MIX implementer, and could be a very simple or complex approach. A client can determine if it has permission to create a channel on a MIX service, which MAY be used to control options presented to the user. This is achieved by a disco command on the MIX service. If the 'create-channel' feature is returned, the user is able to create a channel.

<p>
All messages from MIX channels to participants are sent to the participant's XMPP server. The participant's server will send on these messages to each of the user's clients that has activated the MIX service. MIX provides capabilities for an online client to activate and de-activate MIX for that client. A client MAY activate MIX for all the user's channels or for a selected list. This will enable a mobile client to choose to receive only messages from selected MIX channels. Activation uses an IQ set with an &lt;activate&gt; element to instruct the local server to activate the client. The server responds with a result to confirm activation. The client MAY include one or more &lt;channel&gt; elements, to identify an explicit list of channels that are activated for the client. If mo channels are specified, activation is for all channels where the user is a participant. A client supporting MIX will typically activate MIX as soon as it comes online, but a client MAY also choose to only activate MIX for specific periods.
</p>
<p>
MIX Client activation implicitly verifies that the client's server support's MIX. If the server does not support MIX, it will reject the activation request and the client will not be able to use MIX.
