Well, I have to step up here...

As a developer, I totally support Theo's threat to remove support for 
aac(4). If the hardware cannot be functionally used with all it's 
features, we cannot tell we support it. Especially when there are still 
bugs impeding reliability and that we cannot guarantee on improving it 
because we don't have any supporting documentation.

Concerning the driver removal for release, I just did that for FireWire 
support because I didn't want to lie to our users. As it was unreliable 
and that it didn't support a minimum set of devices, I preferred 
removing that unmaintained code...
This doesn't mean it will never be supported, but just not now.

For aac(4), if we don't get more than distant future promises, why 
should we tempt our users in buying some hardware that could make them 
loose fortunes in data because they will not be notified of disk failures ?
We don't have to take that responsibility...
