(Whats needed, I think, is a cheap box that just does filtering. If it did it in hardware, it could be very fast (needed for high speed lines) and possibly even cheap.

You would still need the software some where in the picture. The hardware in pretty useless without some type of software. Do you know something that I don't? How do you store the filtering paramaters into the hardware? There is still software in the hardware,,,, ----------------------------------------------------------- James 'J.D.'
