nit: Calling this "AllowFoo" makes it sound like it's granting the permission. 
Would RequestMicAccessPermission (similar to RequestMediaAccessPermission above)
work, or does that imply that it's going to query the user?  Maybe
CheckMicAccessPermission?

[Henrik Grunell, 2014/08/25 19:14:13]

Agree. I think "Request..." implies query the user. I prefer "Check..." Will do
that change.

Done.

Security origins can be a bit subtle to get right.  Where will you be getting
this value from?

Ok, sounds like there's an existing (presumably vetted) source.  Works for me.
