I just wanted to point out that multimedia search engines do more than
look at the surrounding HTML–they also parse the media objects
themselves for embedded metadata and do some content analysis. Some
formats (WMV for instance) have hundreds of embedded metadata fields
defined. Others (Real) have hardly any. Content analysis (things like
extracting keyframes, looking at color distributions, etc.) can be very
difficult with things like Flash, because instead of a standalone movie
file to be analyzed you now have an application in which video is
embedded in some non-standard way. Trying to determine where the video
is involves decompiling the Flash application and parsing through the
source… yuck.

I agree that forcing a standard is a bad way to go, *but* there are
things to think about beyond image quality and download size. As Lucas
has pointed out, the situation now with multimedia on the web is like
the text web circa 1995–everyone is concerned with looking slick and
isn't really considering things like accessibility, searchability, etc.

Anyway, these really *shouldn't* be issues for end-users and content
creators to worry about, but until tool-builders get their acts together
and worry more about quality of experience and less about things like
DRM, they'll have to be in the backs of people's minds.
