well it interferes in the sense that it always activates, but it doesn't
need to break native rendering. pmathml.xsl just passes everything
through if running in mozilla for example, so you get mozilla's native

Yes they are the advantages of detection in the client, the disadvantage
is that the client needs to install something first and you get
(typically) less graceful fallback behaviour if a client that hasn't
been adapted is use to look at the page. Ideally xhtml would be
automatically detected in all the major browsers and they'd
automatically dispatch to whatever was needed if the mathml namespace is
there, but with the current generation of browsers that isn't the case,
and I think both methods (and the third method of configuring the server
to serve different versions to different browsers) all have a place,
depending on local needs.

It only works canonically as far as rendering in a CSS engine goes. That
was my point, you lose the benefits of using an agreed more widely
implemented markup. MathML is usable in many places where css is not:
maple, mathematica, openoffice (MS Word2007 as far as I understand,
although I haven't been able to verify that).
