The way discussion on taxation is going globally I wouldn't be surprised if more legislation heads this way, or at the very least a presence test is applied to see if the company has a physical office in country.
There are very specific laws regarding the hawking of shares to the general public without variously being registered securities or having an offering document. While I could see this take off, I doubt it would be used by legal companies unless it could fit within some crowd funded equity carve out.
