Actually ant wouldn't necessarily need to invoke a new version of itself to
build -- it can just load in the classes using a class loader.

By "Ant building itself" do you mean refreshing out the core to keep an
up-to-date version? If so, I could think of doing something like an:

    `ant -selfupdate`

Which would hit the distribution site and see if it needed to get new code.
Of course this wouldn't be default behavior since you don't always have a
network connection. And of course, you don't want to pull straight out of
CVS as that might not be as stable. You'd want it searching on the
milestones or some such.

Or, another possibility is for Ant to check every n days for a new version.
