Show Audio Input Levels on Sessions Page

I'm enjoying Silverback for our usability testing!

Would it be possible to add some type of audio leveling feedback to the Start Sessions page? The iSight preview is great to make sure the user is in the right place. Similarly, it would be helpful to have some indication of the audio levels (similar to Sounds Preferences Pane > Input). That way, I can see that the mic is picking up the user well enough, and that there isn't too much background noise.

Thanks guys, keep it up!
