The reference decoder decodes 640x480 WMV9 material in realtime on my
AMD64 (3400+) but I know in principle that we need the open source
decoder. To that end...

That's the way I usually do it (RE -> English and then re-implement). I
already have several hundred lines written, mostly for the
initialization. I have started with the primary decoding as well,
including CBP prediction (which I have never seen before).
In fact, writing this English language spec is what inspired me to
ponder on my blog about a compiler that could actually compile the spec
directly.

This sounds interesting. How could we structure such a Wiki? I actually
set up my first Wiki last night on my own site, but for a completely
frivolous project. Setting up the MediaWiki software is ridiculously
simple.
