They're moving damn fast about it. Protests and Moby's posts are one thing, but when an administration/state gets involved, and more importantly when money is put on the table, you can tell things are happening. I don't how far this'll go, but I wouldn't be surprised if some places relatively 'close' to SF/Bay (say from Vancouver to perhaps Mexico) became sort of a surburb for less-demanding offices (think: grade A workers/projects in SF/Bay, everything else remotely to save costs and troubles with US immigration).
