I do not even need mod_proxy_http to balance the load. There is a load
balancer for that between Apaches in the web tier and Tomcats in the app
tier. Apache will see just a single BigIP. So, I only need Apache to
handle response buffering for slowly reading clients while Tomcats
continue handling more requests.

Yep, and I do not even need round-robin or failover, my load balancer
handles that. So, I guess I will describe this use case as a feature
request and we will see if somebody feels like scratching it.
