Web Server streaming audio from line in over internet

I am interested in finding out if anyone has built a micro web server that has the sole purpose of taking a line in feed from a 3.5mm jack to stream audio out over internet? If not is anyone interested in making one for me? The smaller the better!

Nearest I have seen is a 4 port IP VIDEO server.
