[AG-TECH] Doorbell for the grid?

G'day All

I thought I might add my 2 cents worth here.  In my opinion, I don't
know if the "On Air" type of thing is really required...  As we have the
tools already that highlights whether (for example) audio is on or not.

The reason that I mention this is because I recently have been
displaying "Rat" on the display screen/wall for users to view whilst
participating within an AG session.  This has multiple benefits:

*	Users can see there audio transmission level;

*	Can see that the "Talk" button is enabled, thereby informing
users they are currently "On the Air";

*	Also allows users access to switch off the "Talk" button if they
require a private conversation.

In my opinion, if we education users, (this button turns talk on and
off, etc) the users will have enough information already to determine
whether that equipment is on or not.  Therefore, why not simply use Rat
to determine is you are "on the air" or not.

Secondly, a number of my Australian colleagues (including myself) have a
portable machine that run continuously in the APAG lobby.  I have found
this invaluable, in which you simply say hello, if you or anyone else
has have any questions, want to conduct a quick test, etc....  The
simple "Are you there Jason" or whoever works well.  And if you don't
wish to be disturbed, you turn off the listen button.  You can also tell
when transmitting a message who receives it (By the green lights within
rat) as well.  

Sending a message through the VenueClient is also useful for getting
peoples attention as well.

So I guess I would like to ask, do we "really need" a doorbell or an "On
Air" function.  I my opinion, I don't think it is required.  Just
educate people with the use of the already supplied tools with the
Access Grid.

Anyway, I am happy to hear other people's opinions and I'm curious to
see what everyone else thinks.

Actually if you are talking about a more or less persistent space, in 
addition the doorbell idea, it might be good to have just a signal that
"Grid is ON" or "Grid of OFF".....even in monitored spaces, the biggest 
concern that participants have is whether the cameras and mics are 
transmitting or not.....some sort of visual indicator would be very
