Output MBP Microphone through airtunes?

[koops]

Just wondering if it is possible to output the microphone sound through to airtunes?

What i have in mind is just me playing some tricks on my brother downstairs (where airtunes is setup) and i can then use my micrphone to speak through the speakers downstairs?

Is this possible?

Ever figure this out? I have an airport express in the basement for the kids and I would love to be able to tell them to stop fighting or whatever else they're doing.
