PFR and NAT design assistance needed

looking for clarification and design assistance with PfR (performance routing) and dual ISP connectivity.

I'm concerned by this statement in the 15.1M IOS config guide for PFR:

Note

The PfR static routing NAT solution is a single box solution and configurations with interfaces on multiple routers using NAT and managed by PfR are not supported.

This appears to be supported scenario

PfR with NAT

supported because MC and BR and NAT awareness is all on one platform?

This is another diagram from same PDF:

Master Controller and Border Router Diagram

This makes it seem like separate BR's connected to different ISP's is valid.  This would represent a case where different NAT rules are in place to translate packets to the outside interface.

Seems like there might be some nuances to exactly what topology is supported and what is not.

Goal:

I have a customer that wants 2 different broadband internet circuits connected to 2 different routers (for hardware redundancy) and would like PFR in place to utilize both links simultaneously.

Anyone have this scenario working anywhere?

Thanks in advance,

Paul
