Pete, Thanks for this - I'll watch that preso and see if it adds anything useful.
You seem to be supporting my viewpoint, and I've also had an off-list reply supporting TAC's viewpoint - so I'm not sure I'm any further forwards. I'm currently working on a plan to replace the ESP40 with an ESP100 - but as the ESP100 isn't supported in the ASR1004, I'll also have to do a chassis swap to an ASR1006. My only remaining concern with this plan is whether the SIP40 can really do 40Gbps. If I stick 4 * 10G SPA's into a SIP40, can I run those 10G ports at line-rate (assuming sufficient ESP capacity)?
