Based on the contacts I have received, it appears that there are a
number of companies who have microphone array, noise reduction, and
acoustic echo cancellation products, who are concerned (with good
reason) about how their carefully constructed algorithms can participate
in Vista.  It seems to me that most of these companies do not really
care very much about the infrastructure; they want to be able to supply
their own algorithms, based on their own research by their teams of
big-brained algorithm specialists.

It has occurred to me that it might not be too difficult for Microsoft
to provide a plugin interface to the existing AEC GFX module, thus
allowing these companies to integrate their own algorithmic libraries
into a known-good GFX infrastructure, without having to reinvent the
user interface aspects or the installation and system integration headaches.

I'm wondering if that approach has been considered, or if the answer is
just "rewrite the whole GFX".
