Thanks Steve. I do already have an iRule set up like this, and it works great, but requires an HTTP header utility or Wireshark. I also have an iRule that updates log files on the client (but the developer doesn't have advanced enough access to view those logs.) The developer keeps hounding me that he's seen other load balancers with the ability to ping members, but I'm still not finding any information that it's possible. I was waiting to get my F5 support ID approved, which it is now, so we'll see what I get officially from support.
