One of the main complaints I've heard about chaining topology for servers is
that the reliability now drops a lot. Any failure on any server cascades
through all the rest down the chain.
Have you looked at the multicast stuff instead? That scales as O(1), and
doesn't suffer the multiple single points of failure.
While chaining might make sense in very specific environments with specific
assumptions, I'm not sure you can general case it enough to make it useful
in systemimager upstream. I could be wrong, but that is just my first take
on it.

There is no silver bullet. Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
