I'll answer you, if I may.
You have to go back a little bit to the meaning of a parliament. A parliament is first and foremost an assembly, or a meeting of people who exercise the legislative function. In this case, the physical location is of secondary importance. The essence of what a virtual assembly is can be fully respected as long as, as I said, a number of conditions laid down in the Constitution are met.
In the specific case of section 49 of the Constitution Act, 1867, physical presence is not required. It simply imposes a rule for the holding of votes, but there is nothing to say that these votes can't be taken virtually. It says that the majority vote prevails, and that only in the event of a tie vote can the Speaker vote.
