Make ant quiet without the -q flag?

I have an ant buildfile that is often run from vastly different environments. By default, I'm looking for the same behavior as using:

ant -q

However, since some team member's configurations vary, specifying the -q option in each person's environment is not easily accomplished in a uniform way (some people run ant from eclipse, some from the command line, some from debugging/profiling tools, etc. Each with a different method for specifying ant arguments like -q)

So I'm seeking a way for the ant file to call itself quietly...

Something like the following would be ideal:

<target name="default">
    <antcall quiet="yes" target="build" /> <!-- doesn't work -->
</target>

Can anyone think of anyway to accomplish something like this? All I'm after is for the build to run quietly whenever the default target is ran, regardless of whether -q is set.
