Customizing the Error Activity Space

Question

I'm doing a rush evaluation of using google appliance to crawl our guest-readable portal. We have numerous issues that i'm trying to work around, but one is that a lot of error pages are being indexed.
Is there any reason why the error space returns a status code 200? Can it be easily modified to return 500?
I've asked these questions before, but has anyone done the leg work to configure the portal / google appliance so the crawl works correctly? What url patterns did you set? What does your robots.txt / nofollow meta tags do? Where do you put googleon and googleoff?
Thanks!

public class CustomErrorDP : ErrorDP
          private static OpenLogger log = OpenLogService.GetLogger(OpenLogService.GetComponent(PTDebugHelpers.COMPONENT_PORTAL_BROWSING),
               "com.plumtree.portalpages.common.error.CustomErrorDP");
          public new const string STR_MVC_CLASS_NAME = "ErrorDP";
          public override void Display(IWebData pageData)
               base.Display (pageData);
               pageData.SetStatus(500);
               log.Error("Status set to 500 in CustomErrorDP");
     public class CustomErrorAS : PlumtreeAS
          private static OpenLogger log = OpenLogService.GetLogger(OpenLogService.GetComponent(PTDebugHelpers.COMPONENT_PORTAL_BROWSING),
               "com.plumtree.portalpages.common.error.CustomErrorAS");
          public const string STR_MVC_CLASS_NAME = "ErrorAS";
          public override object Create()
               return new CustomErrorAS();
          public override string GetName()
               return "ErrorAS";
          public override void Init()
               log.Info("CUSTOM: Starting init");
               base.Init();
               this.RegisterPage(new CustomErrorDP());
               this.RegisterModel("SinglePageErrorModel");
               IModel model = this.GetModel("SinglePageErrorModel");
               this.RegisterControl("SinglePageErrorControl", model);
               this.RegisterView("SinglePageErrorView", model);
//               this.GetCurrentHTTPResponse().SetStatus(500,"Custom Error Message");
//               this.GetCurrentHTTPResponse().AddHeader("Some stuff", "More Stuff");
               log.Error("CUSTOM: Finished custom init, set header to 500");
