This is certainly not the first request for a nice high-level picture of
the Daala encoder and decoder. I'll see if I can draw an up to date one
and add it to the wiki.

Both hardware and software decoding of Daala is meant to be practical
across a variety of devices, including mobile chipsets.

Daala is feasable with a JS shim, however we would much prefer to be
natively implemented in devices and browsers. You can see an example of
this being done for other free codecs here: https://github.com/brion/ogv.js
