No, I haven't. I used to use google hangouts, and then it went away.  
Now that you mention it, I do see something when I log on to gmail  
offering me to use "meet." Actually I seldom go to gmail. It's a  
*terrible* interface. I use POP to get the mail and read it with Balsa.

I have not checked out any of the new google meeting things, nor have I  
tried webx yet (although I mean to do that).

I haven't used it for a long time.

If I hear anything to indicate that any one of the above really works  
well, I'll give it a try. But "give it a try" (to really determine if  
it's going to work for the group) is a procedure involving multiple  
(busy) people for a non-trivial amount of time.
