System-wide DSP

[gandalph]

I'm looking for an app that will allow me to run DSP on the main system audio out. What would be really cool is something that works a bit like Reason (with the different racks and whatnot) but is real-time. I'm mainly interested in a compressor, but a delay would be kinda nice too. Anyone know of such an application?

Anyone?

would most likely have to be built into the drivers for it to effect all sounds.
