I don't think that contradicts what Joshua says (or if it does I have a 
problem because I agree with both of you ;). Yes, the most interesting 
part of SVG is when you use the complete family of specs: you get a 
complete and modern graphical toolkit that's extremely powerful and 
rather easy to use. Currently, it's true that the only serious option 
(that I know of, on the desktop) is Adobe's Viewer (Batik in some cases, 
with a heavy biprocessor and ~2gigs of ram). I think however that were 
ASV to disappear tomorrow, it wouldn't be long before an open source 
gorilla would get into gear and implement a complete viewer. One good 
place to start would be to finish the Mozilla implementation (because 
it's guaranteed to be portable, and you have a lot if not most of the 
technologies you need already done). Another place would be KDE which 
already has Konqueror and kSVG.

Not that many, but imho enough that a viewer would be implemented rather 
fast should a strong need arise. I think we will see complete 
implementations other than ASV some time in 2003.
