This isn't really something that BIND does well natively, but you can beat it into submission if you care enough. Depending on what your application is it may be chapter to simply just buy a commercial product for this -- I'm guessing you've already gotten a bunch of replied from folk offering to sell you such a widget…

By using dynamic updates and a small script to do the health check you can fairly easily cobble something together to do this. A long time back I write something that talks to Nagios and added A records when servers were up and pulled them out when the server went down. Worked fairly well, but ended up being more trouble than it was worth...

If you also want geo type stuff:
