I'd considered it a lot lately, but decided against it, as it's not as 
hassle free as you make it sound: the biggest problem is configuring the 
DNS, so I don't see what the feature would add.

With TC 5, you can dynamically add hosts with:
- JMX (using some agent)
- the admin webapp, like in TC 4.1.x

I think that's good enough, and the extra complexity doesn't seem to add 
something of real value.

I'd vote -0 or -1 on the issue.
