Yes you can use this method, and with the current audio tag and
autobuffer, it may work to some degree.
We've used the data:audio/midi technique, and we've experimented with
using the data: injection work-around, does not currently work all that
It does not produce smooth transitions. We can use raw encoding instead
of base64 to save on
cpu cycles, but it's still quite "hackish".

Overall, we can not make near-real-time effects, nor jitter-free
The data: injection technique is inefficient, it's not workable.
Opera has been championing Xiph codecs on this list, There are
ActionScript and Java Vorbis-players developed using the most basic of APIs.
Isn't that use-case compelling enough?
