I'm delightfully surprised at how much attention Mozilla is apparently giving SVG. First they've hired jwatt to work full-time on SVG. Now it looks like some students also have an interest in advancing the SVG implementation within Mozilla. Great!
I don't have the experience of a seasoned Mozilla hacker (only a couple patches years ago), but I do know that SMIL, SVG Fonts, SVG in CSS and SVG text-specific edge cases could use some work from a SVG 1.1 perspective. Hopefully they get in contact with jwatt, rlongson, roc, dholbert and birtles and get some ideas rolling...
