I missed part of this thread, but I gather that though SSO was in earlier 
12.2S releases (12.2(18)S6 for instance), it got removed in or around 
12.2(25)S and won't be back any time soon?...or may be back in a special 
12.2S[A-Z]* release specific to the 7500?

We're still using these (with redundant RSPs) for MPLS VPN aggregation 
(mostly FE subinterfaces in VRFs).
