fwiw, I recently made some experiments using an instrumented
flash decoder.  I've focussed on the vector data representation
(as the spec says, "many SVG files will be dominated by their path
data"), and it looks like zip-compressed SVG path data is about the
same size as the corresponding *uncompressed* Flash shapes.

On the other hand, most Flash files also get smaller if you
compress them...

Anyway, I plan to run these tests on a larger set of sample files
this weekend.  Stay tuned.
