This would make it super simple to setup a mining farm.
I assume there is multi-GPU support.
I hardly think Javascript & WebCL would be more efficient than C and OpenCL.
He forgot to add the word 'botnet' before 'mining' ... since that is really the only valid reason for this.
Any excuse they come up with is just total bullshit.
Who in their right mind would want to use up buckets of CPU/GPU and mine at a much slower rate than any readily available mining program?
... especially since at the moment there is no way you could do this so that it would cost less to mine that the BTC you would earn when the miner itself would be slower than a dedicated miner that already is borderline to running at a loss
Again it's just people trying to steal CPU/GPU cycles or idiots mining at a loss.
