I just spoke with a Nvidia representative using this chat http://nvidia.custhelp.com/app/chat/chat_launch
After I asked if the gtx 1080 Web Drivers where currently available, he replayed that they weren't currently available. However when I asked him if he could confirm that the drivers were in development he replied with this:
"The GTX 1080 is not officially supported with MAC OS, but there would be drivers which support Pascal cards on MAC in the near future."
So it seems he has confirmed that the Web Drivers are at least in development.
