Thanks for the detailed information, and for the explanation of your

I'm glad to hear that the infrastructure is in place, and that it will be
leveraged going forward.  Having all page content zoomable is good from an
accessibility standpoint, so I applaud that decision.  SVG will be very
effective there. 

Of course, you should do whatever you think is most compatible with your UI
in general, but as an author (not as a member of the SVG WG), I personally
disagree with this decision regarding SVG-specific zooming/panning on 3
1) it will not match the behavior of Opera or ASV (dunno about Safari); 
2) it is inconsistent with how rasters are treated;
3) for mapping applications and other uses, it would be very nice to have
native zoom/pan/rotate.

But I suppose your usability testing and user feedback will prove the most
compelling argument.
