So, what do you do for a remote meeting with participants in different places? You’d have to decide on one location. Specifying Paris when you are really in Toulouse isn’t much different. Yes, your meeting is now bound to Paris time, but at least it remains consistent with that.

Furthermore, having had to work with call routing based on geolocation, I can tell you that geo coordinates aren’t always enough, due to inaccurate zip code and area code divisions and other factors.
