Use an External Custom Field

The example code fetches groups, but could easily fetch Users.

You can actually do this, it's completely unrelated to a custom field.
You need to use the CreateRoleGroup method to create a new role group
and also RegisterRole the new group.  There's some significant peeking
under the covers here, but the code was all implemented explicitly for
assets and is used by a client who has non-standard roles on their
assets.
