Software to act as sound card and transmit across network

Question

Does anyone know if there exists any software to create a virtual sound card on one computer and send sound data across the network to another computer, where it also appears as a virtual sound card?

What I'm looking for is something like this, in software, via the network:

Computer 1 (Virtual Sound card)             Computer 2 (Physical sound card)
Mic                             <-          Mic
Line out                        ->          Line out

Computer 2's physical sound card would probably be linked to a virtual one that did the I/O over the network, I imagine.

The reason I need a virtual sound card is so that I can set my voice application to use that sound device rather than my system's hardware sound device (ie, Audacity's playback and recording device selection).

Both computers run Windows.

Does this exist? I would prefer free software, if possible.

and here's a Guide to setup and configure Shoutcast for LAN audio streaming

Answer 2

You may want to see if pulseaudio meets your requirements.

PulseAudio (formerly PolypAudio) is a cross-platform, networked sound server project. It is intended to be an improved drop-in replacement for the Enlightened Sound Daemon (ESD). PulseAudio runs under Microsoft Windows and POSIX-compliant systems like Linux. PulseAudio is free software released under the terms of the GNU Lesser General Public License (for the software library portion) and the GNU General Public License (for the sound server itself).

If the machines are both macs, you could use SoundFly.
