Ok, so I tested the multipool at Chunkypool for 24 hours, a gpu running scrypt -vs- my usb antminers as a comparison to see which made more bns, results below.

8 x usb antminers @ 16ghz = approximately 8500 bns in 24 hours.

1 Radeon 7850 @ 340khz = approximately 13000 bns in 24 hours.

I did not expect these results, it's a lot better than I expected.  Just figured I'd throw that out there for scrypt miners who are not sure if it works, it does.
