XProtect Incident Manager and Milestone Federated Architecture
You can use XProtect Incident Manager on an installation that is part of a federated site hierarchy of parent/child sites.
You can use XProtect Incident Manager on all sites with a base license for XProtect Incident Manager. You can add sequences from your own site and its child sites to your incident projects.
However, the incident projects are only available on the site they are created. XProtect Smart Client operators working on other sites - parent or child sites alike - don't have access to the incident projects even if sequences from their sites are added to the incident project.
