Ah of course - I get you. So if it were part of the monolithic firmware install then anyone targetting WebM could be assured that it would work on n900. And of course in microB, which I imagine is your point - I was only thinking about having the codec available on the n900 but to use it in a web setting, microB would need to know about it, and if firefox is anything to go by, this means baking it in. Or a plugin perhaps.

Ah well. Perhaps one day!

It seems pretty likely that vp8 / webM will gain momentum pretty quickly. I for one am already impatient.
