Hmmm.  Do you have complete URL to that posting?
I am re-subscribed to www-SVG mailing list again (just few days ago), but 
haven't seen that mail.

Is it Bad or Good?
Good photography is about 15MB-30MB in size.
Do you really want to put such image on web, especially in SVG wrapper?

From my expereince, scaling images to small sizes doesn't work well.
I have tried different packages, differetn filters- and it's all the same.
Either you have enough pixels (high dpi value) or you don't.

Indeed, they rescale.  Looks interesting ;-)
Why don't you use SVG graphics than?
I think it would be more natural.

|  great to see your lovely icons.

Do you want me to help with some of icons?
That site looks like quite inetresting.  Where do you get current pictures
