Discovery of failover peer using iControl

Yep, on v10x the LTConfig method works fine. I tested against 9.4.0 and I get SOAP-ENV:Client : Unknown method "{urn:iControl:LTConfig/Class}:get_list_of_instances", and under 9.4.7 I also get an exception (although with slightly different error text). I'm convinced that the only reliable method for finding a failover peer is to somehow get the peer's management IP address, so I guess automatic detection of failover peers will only work for v10 and higher, which is just the way it will have to be. I will however be able to make a reasonable guess at failover peers for versions <10 by doing some logic using the "might work" methods we've discussed, and then at least present the end user with something like "hey, we think these are a failover pair, is that true?" dialog. So, unless anyone has any miracles to tell me about, I think it's safe to say that for versions < 10 you cannot reliably detect the failover peer managment IP address with iControl.
