Thanks, I will keep an eye out for John's build plan work (I assume it won't
be available until some major release).
If we were working under Linux I could probably tee the output then gawk it
to find what project and phase it was working on and then used that to
generate what I need.

For now I have put together a plugin echos what project and phase is being
executed (it also shows a timestamp).
I just have an <execution> block for each phase, and inside it a
<configuration> variable that has the name of the phase.

Thanks Again.

P.S. If it isn't obvious, I am a maven newbie
