sandboxing audio applications

We have a bunch of audio playback applications that use a variety of APIs that fall under CoreAudio.

for Core MIDI we can use

<key>com.apple.security.temporary-exception.mach-lookup.global-name</key>
<array>
<string>com.apple.midiserver</string>
<string>com.apple.midiserver.io</string>
</array>

for Audio Units we can use this in the short term, until AU authors get on board with sandboxing their audio units

<key>com.apple.security.temporary-exception.audio-unit-host</key>
<true/>


the problem we've run into is relating to Audio devices that have their own drivers and we don't gain access to be able to play/record audio.  I have already filed a a radar against this as its a pretty serious problem for us currently. rdar://problem/12836341

the gist is, without specifically calling out each device's driver in our entitlements we can't talk to this pro level hardware and maintaining such a list of what devices our users might use is not really an acceptable solution for this problem.

any comments from the CoreAudio team?
