point #1, i'd still have to disagree with. that's going to be part and
parcel of almost any load-balancer configuration, regardless of what you
call it. the actual cli is still much closer to ios/mqc than it is to
arrowpoint/webns, no matter the name. examination of 'show run' on the css
vs. the ace illustrates the point pretty well. point #2, i was not aware
that there was feature disparity in that regard between the appliance and
the service module. interesting. point #3, what specific information would
you want to insert? the certificate info/signature that the client is
providing? i must admit ignorance on this part - i've not had much
experience with using client certs in this manner.

 Hi.                                                                                                                                                  
                                                                                                                                                      
 In fact there are similiraties between CSS CLI and ACE CLI (rserver, servfarm, inservice...)                                                         
                                                                                                                                                      
 Also OSPF RHI is supported on ACE module (not appliance and it's not on the radar as far as I know).                                                 
                                                                                                                                                      
 Also when using SSL offload, inserting SSL infos related to a specific session (client's certificate insertion) is currently not available.

  i'd have to take exception to this. the cli is nowhere near to being close                                                                          
  - the ace is far closer to mqc on ios than anything the css or arrowpoint                                                                           
  ever did. i'm also pretty sure that in A2(1.0) and later, rhi is supported

  Just a quick comment on this point, currently, if using SSL offload, ACE (module and appliance) don't support certificate insertion in HTTP

  also it's not GSLB capable (Cisco use another appliance, the GSS) and OSPF RHI for VIPs is not supported on the appliance (but you can use an IP

  If you want to stay with the same vendor check the feature parity between the ones used in your CSS config and the ACE (appliance, the module       
                                                                                                                                                      
  requires a Catalyst 6500 chassis with a sup720 and the whole bundle is quite expensive :) )                                                         
                                                                                                                                                      
                                                                                                                                                      
  Also there is a migration tool from CSS to ACE configurations (the CLI is pretty close)                                                             
                                                                                                                                                      
                                                                                                                                                      
  My other experiences : all LB vendors (cisco, f5, citrix, foundry, radware...) implement the same features so go for the easiest solution to manage

    If you are a Cisco shop, take a look at the ACE appliances.  Before you buy,                                                                      
                                                                                                                                                      
    make sure that your existing requirements/features on the CSS are well
