That's great news.

If the client gets back some kind of connection-refused indication, it 
will immediately move on to the next KDC in the list.  If it sees no 
response at all, it does wait a little (one second, I think) before 
moving on to the next KDC.  So, yes, there's a delay, though it 
shouldn't be large.

I'm afraid not, in the current version, unless you do it through DNS 
(SRV records, or one KDC with multiple A records), which you say you 
can't... :-(
