Well, there are two companies that I can think of to get you going on this.

First, Turtle Beach Softworks has announced a 56k card for the AT.  I don't
know the price off hand, but it's a place to start.

Second, a company called Spectral Synthesis makes a system based on TI's
32C020.  Each of their cards has two DSP's on board, and you can connect
up to seven cards in a system.  They can get you going for about $2000, but
when I last saw their software, about eight months ago, they were not ready
to ship just yet.  Their software is called AudioCAD, and basically it lets
you connect fundamental blocks (mixers, amplifiers, etc.) graphically under
windows, then it compiles the code and assigns it to the bank of DSP's.
Their big goal is real time processing, so the have a neat set of resource
allocation routines, and process scheduling system to best use however many
DSP's you have in your system.  A full blown system is about $10k.  Oh, and
you can write your own primatives too.
