I like the new offering for your DualMiner 2 ASIC but can you tell me when you intend to create a mining app to run this ASIC on my Mac?

Also when I see a new revision no in the name,I usually expect higher performance or reduced energy use if hashrate is the same.Is it even possible to increase the scrypt hashrate of the DualMiner or would running off a USB port prove too difficult (as there's not much of a power envelope)?

I'm just curious to know.Thanks
