Required: PAN IPSEC Hub best practices for 300 route based IPSEC tunnels

Pan documentation is very weak on large scale mutli-vendor IPSEC hub terminations.   Can someone help out and provide best practices, reference architecture, guides, pitfalls or experiences?

My design goals:

     -  Separate VSYS

     -  Use dynamic routing for Tunnel Interfaces. (Either OSPF with stub areas to inject default to remote tunnels or RIP)

     -  Tunnel Interface network routing summarization for optimal system performance with maximum spokes per tunnel.

     -  Separate virtual router for un-trust interface VPN termination with  separate virtual router for tunnel and trust interface.

     -  IF OSPF maximum spokes per OSPF Area.

     -  Dynamic routing protocol for VPN VSYS is an autonomous system, BGP summaries are used for trusted network routing.

  

My environment today is multi-tenant 7050 design utilizing BGP \ OSPF for segregated departmental internet with 50,000 users in multi-vrf interconnectivity.   This VPN service is another layered virtual system that will be collapsed as part of our firewall consolidation project.
