Let me chime in here since Marty referenced the BU site.

At Boston University we have 8 table top mics positioned so that they 
are on tables in front of the audience members. Our space is configured
with 8 tables and one mic per table.

Frequent visitors find it easy to use.  They mic itself has a single red 
LED and a button labeled "touch"  When the button is presses the light 
toggles on/off and the lit state represents the "open mic"

Users have fighred out that they can have the normal whispering to thie 
neighbor happen - just like a real meeting - if they tuen their mic off.

For us in the more formal seating arena we use works very well - it is 
easy to see the status of the light and easy to toggle it - I'm not sure 
thie approach would work in other room configurations.
