That will allow something converting the snapshots into another format to know how to convert them.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'd go with a different approach for storing the various snapshots. An ao2 container, while useful if you want to look up a single particular object, is overkill when the pattern of usage is to iterate over the entire container.
Generally, payloads are always consumed in whole - it's rare for anyone to only want a single part of the payload. This is particularly true for payloads with multiple objects: you generally will convert all of the objects in it to JSON, or AMI kvp, or something else.
I'd just store the snapshots in a wrapped struct (like you have) that is a tuple of (type, snapshot) in a list or a vector. That has the added benefit of not requiring a custom hash function.</pre>

1) Existing channel_user_event stasis messaging replaced with new multi_object_blob in stasis_user.c
2) Multi object blob provides ability to signal blob + any number of channel, bridge, or endpoint snapshots
3) Changed existing Userevent() app to use new multi object blob - but still publishes to channel
4) Added ARI implementation of userevent as /ari/applications/{applicationName}/user/{eventName}
5) ARI generated userevent messages are published to application, and also to AMI if channel present</pre>
