Plugin?
"We question whether yet another plug-in is the best of ideas"
Erm, where's this plugin? The idea is to replace all these terrible plugins (especially the egregious Flash) with built-in browser support.
If some variety of VP8 were to be released under a useful license then all browser vendors could link in nice, fast support using native, hardware renderers like GL or overlay. Fast loading, high performance, really cross-platform web video. Wouldn't that be nice?
Apple's patent FUD notwithstanding, the VP8 codec is only realy necessary if you find theora's btistream that inefficient - there are constant improvements in the encoder. Recent comparison here:

Shatner is looking pretty these days... be nice if it had a low bitrate video comparison available, though.
