Thanks. I had missed the ES+ line cards since they are a bit obscured on the main web page of the 7600. I'm definitely going to run everything by/through cisco, but my experience is that if you don't know enough to ask the right questions, you end up with whatever hardware they are pushing that quarter.

If you are going to spend the money on ES, a few words of warning about ES-20. It is very limited in terms of what the card can actually do in terms of QoS (for example, there's no tuneable Tc for any policy) - additionally, everything needs to be under a class-default on sub-interfaces for example. We found that this has severely limited a number of QoS deployments that we've tried to do. SIP-400 is actually better than ES-20 - I'd look at ES+20/ES+40 for your requirements. LAN cards don't seem the best way to go if you need such strict control. However, I'd put together a strict statement of requirements and get Cisco to demonstrate that the card meets your demands before you go forward. The 7600 platform can have a nasty habit of biting you back. I can probably share more details of the ES off-list if you need them!
