The following portal component could be used to replace your masthead iView . Basically it makes a small table which has the normal masthead plus a bit of code that works out which host you're on and puts out a message,
Make an iView from it and add it to your framework page in place of the regular masthead and you'll then get the appropriate information.
public class WhoAmI extends AbstractPortalComponent
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
          IPortalComponentProfile profile = request.getComponentContext().getProfile();
          StringTokenizer st = new StringTokenizer(System.getProperty("SAPMYNAME"),"_");
          String message1 = "You are on the ";
          String host = "development";
          for (int i=0;st.hasMoreElements();i++) {
               String s = st.nextElement().toString();
               if (i==0) {
                    if (s.equals("abcdef")) host = "production";
          String message2 = " server";
          response.write("<div id=\"WhoAmIArea\"><table width=\"100%\"><tr>");
          response.write("<td align=\"left\" width=\"90%\"><iframe width=\"100%\" height=\"38\" src=\"/irj/servlet/prt/portal/prtroot/com.sap.portal.navigation.masthead.default\"></iframe></td>");
          response.write("<td  align=\"right\" width=\"10%\">");
          response.write("<span class=\"urTxtStd\">"+message1+host+message2+"</span>");
          response.write("</td></tr></table></div>");
