Great way to integrate IOTA and the Ethereum network to achieve your goal. My questions:

Can websites running the Oyster script be opened using any browser (including something like Brave)?
Is there a way to adjust the amount of CPU/GPU used? What if multiple websites are opened -- is there crosstalk to prevent CPU/GPU from overloading?
Am I correct in understanding that the value for content publishers is to get Oyster Pearls from visitors, which they can then sell on an exchange?
Is it possible for content publishers to offset hosting costs by using the Oyster network for uploading their website content?

Interesting find. When did that happen?
