Mark Pilgrim rants about something to do with Apollo, Flex, Flash, etc.
Not that Apollo is the final destination, but it is a helluva better step towards something useful than the place browsers seem to be going anytime soon.
These things *are* becoming more open and they are "on the web". And they are a helluva lot more programmable than browsers.
How long as SVG been around? And it can do what, again? With how much complexity?
Have fun. Fuzzy explains it.
