Also when you say multiple cards are you referring to SLI (or crossfire) or just a "put different gpu on the same motherboard" and make them work ? Because for the first option looks like opencl is not ready enough (at least on ati) and for the second one something could be done "manually" with some coding (i'm thinking about nasty tricks with clGetDeviceIDs and some shell env variable) . > - Consider add support for WPA/WPA2 handshake.
