My main interest in this article was not about Singapore, but at what point does an online gathering cross the boundary to the physical world where limits are placed on the size of the gathering, or if and when it crosses countries' borders. What's not to say the HKer was the host and the Singaporeans were individually the guests? Obviously that isn't what the court decided in this instance but perhaps that is what could happen next time. Was it the physical location of the Singaporeans that made the difference? What if they had attend a Skype concall at home, would the court be looking at who sent the meeting invitation?
