Perhaps not a bad idea, but adding code to support decoder embedding, would
probably make the basic player larger than 30kB :) The small size is also
achieved by optimizing and packaging the player as a whole. If I package the
Ogg demultiplexer and the Vorbis decoder separately, they end up at 18 and
26 kB each and in addition to that you need the player code. The most
reasonable usage for the applet would anyway be to host it together with the
stream itself, so I think it would then make more sense to package a
customized applet for this specific stream (if it uses a non-standard
format) and then run that jar file through a code optimizer.

I think your idea would fit better in an installable player and perhaps not
embed the decoder itself in the stream, but a URL where the codec could be
downloaded. In that case the player may choose to implement some sort of
plugin cache to minimize downloads.

Anyway it's perhaps not a very good idea at all to encourage the use of
non-standard formats :-/
