There is a cheaper head mounted mic option that isnt as
compact/invisible. Just to point out, this is what we used at PyCon so
you can see (and hear) the devices in action in those videos.

The only complication with these other approaches is that, when/if we
have multiple parallel streams one day, we'll be limited in our
approach. We know that with this proposed solution, there are 12 clear
channels to use side by side: that's 6 streams of 2 wireless mics per
stream (presenter, audience).

Bringing one of the new laptops with me tonight to the Moon & 6.

I feel that, since we have the grant money, we can afford to do this. We
will still have our Boundary mics, and any handheld wired mics we want,
plus the audience wireless mic. We've never needed two wireless headsets
thus far, despite changing our format around - and if we do, we can
alway use the cheapy one we already have for the secondary presenter???
