Lava Mike

• See comparison of lavalier mike, dedicated digital regorder without lava mike, shotgun mike plugged into camera, or separate recorder + boompole. [1]
• Shotgun mike on a camera may be a good option.
• Lavalier mike + cell phone may be good.

This is once again a field where many solutions exist, and all of them are suboptimal and could benefit from open source collaboration.
