You don't seem to know that ASV 3 is a high performance dynamic SVG
viewer (well it meets the relevant part here) if you open a large SVG
document, then you will see content rendered whilst the rest of the SVG
is being downloaded, if you look at
(which is ~400k IIRC) you will see various details and a photo appear on
the screen whilst the audio, and slide data is still being downloaded.
This seems to meet your above situation without problem (and is all that
flash has AIUI other than loadMovie for loading in new movies which is
scripting)  The way current SVG implementations differ from flash is with
included content - flash can progressively "render" mp3's, ASV can't, you
have to have the whole mp3 downloaded before it can play.  That's not an
SVG issue though.
