Question: Can I use stream-framework for fanout to target object followers

[aammundi]

It's clear that I can use stream-framework for Notification/Activity feeds. However, the use-case I'm building involves a slightly different scenario

1. A per-user ranked feed of target objects. An example of target objects could be movie listings.
2. A per-user ranked, filtered feed of users who follow a target object

As far as 2) is concerned, it seems like I can override get_user_follower_ids to accomplish this [user->target-objects-the-user-is-following -> user_ids that follow the target objects]

Would this be a good way to handle this scenario ?
