Good luck Pg, I am very interested in how things pan out. I have the
routing capabilities ready using pgdjikstra, but have not had any
success implementing a frontend for ka-map (Same problems with slow
rendering using wz gfx)

It's slow and heavy, not only in Safari :-(
I'm not sure if it's due to the large amount of <div> generateb by
wz_jgraphics, or to the periodic XML parsing and related coordinates
convertions, or to the extensive use of transpareces.

And dulcis in fundo it's not working so well on IE...

In any case I thik this way is good to plot few points, labels, icons.
To draw complex features I'm looking to the other solutions soggested
by Paul.

- Server side images are not affordable for "big" features, that
zoominig in can produce very big images (and I'd like avoid tiling
that images).

- SVG seems to be a good idea (at least for Mozilla family), but it
should be generated on the server in screen coordinates. I will do
some experiments soon.
