I'm certainly in favor of something like this.

In my case, I still want the build to fail, but I
want to send an e-mail to a text pager. Right now, I
do this by doing an 'echo' to a file before a
task starts, and a 'delete' of that file when the
task finishes. After the build, I run Ant again
with a different XML file that uses 'available'
to find any of these temp files. If it finds any, it 
sends the e-mail. Crude, but it works...

I'd much rather have the build do it's own thing...
