Breakaway Pass Through

Is there a way for Breakaway to capture a signal from my computer’s mic/line in jack? I would like to be able to take an outboard signal and run through Breakaway, basically inserting Breakaway into the signal path? I’m an amateur musician, and I make recordings on occasion. Generally, I capture these recordings on a media, then play them back through a computer (one which doesn’t have Breakaway, and would not have the power to run it while recording) to record them to a digital format. I’d like to be able to run the signal into Breakaway and process the sound as it’s being recorded into the computer. Is this possible, or would it be something that might become possible in the future?

The computer with Breakaway has a 2.2Ghz Core 2 Duo processor with 3.5G of RAM running Vista buisness. The recording computer is running XP home. I don’t have the specs on it, but let’s just say that if the one with Breakaway is a Corvette, the one with XP is a powered wheelchair.
