In the future, browsers should support SRV records, which would provide
this functionality.
For now, there is no good way to do this with DNS alone. You could
reduce the cache persistence down to anti-social levels (e.g. 1 minute)
and then manually change the address as necessary, but that's definitely
a suboptimal way to do things.
