[LAU] Any support for MADI?

The venue where I work has just been given a new Soundcraft Si3 console (Thank you Harman!). There is an option card available for this console which provides direct outs via MADI56 or MADI64. Does anyone know of a piece of supported hardware that will allow me to record shows on my laptop with Ardour? -- Rick Green "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -Benjamin Franklin "As for our common defense, we reject as false the choice between our safety and our ideals." -President Barack Obama 20 Jan 2009
