We are working on coming up with clear strategies for Internet Explorer and hope to update developers on that soon.  I would, however, suggest that you avoid UA string detection and leverage the built in hasFeature in the DOM to detect SVG support, as well as more granular hasFeature in SVGDOM, and declarative <switch>.

I'd LOVE to see use cases that you are trying to cover.

Hi, folks-

Just to clarify, when I said "more functional", I meant specifically for the following three features:

1) SVG Fonts: the full profile of SVG Fonts, i.e. SVG fonts with arbitrary content, rather than simple path syntax

2) Declarative Animation: ASV had fairly good (though not great) SMIL support; performance could have been better, but they had a fairly full feature set.  Firefox may have SMIL support, and there is interesting stuff going on with CSS animation as well.

3) Filters: ASV had fairly complete filter support, unsurprisingly, since many of the filter primitives come from Illustrator and Photoshop. 
  Firefox has made a lot of progress here, actually.

I don't think IE9 will support any of these three, but it (and the other
browsers) will do other things better than ASV did, like HTML integration and hardware acceleration; but these areas of improvement aren't the features at risk for legacy content, by definition.

Note: Opera has fairly complete SVG support, so I'm less worried there; WebKit also has pretty good SVG support, though Android turns it off for now. :(

So, the question remains... how to best manage the transition?
