Hi,
another idea that could be nice for SOC could
be a symbol server that can works standalone,
or be used as a remote source of symbols.

What I envisage is something using the GT2
dynamic symbolizer factories, and that exposes
them using a REST api that clients can
use to:
- inspect what symbols are available and what
   parameter each symbol has
- push more symbols into the server (or
   delete them)

This could be used by clients like GE that
need to grab symbology from a web accessible
source, and from styler like projects that
need to present users with a choice of available
symbols.

Symbol wise, the server could provide:
- plain raster symbols (png/jpeg)
- scalable ones (svg) and allow the user to ask for a rasterized
version at a specific size
- marker related symbols as well, with
   parameters about size, fill and outline
   color (wihtout going into full SLD power
   thought, the params would explode in that case)

And interesting extra spin would be to have this thing
serve charts as well, like DeeGree is doing
(http://conference.osgeo.org/index.php/foss4g/2008/paper/view/332/168).
Ok, we can do that already using Google charts api, but that's
not very good from a perf pov, plus we could have the
chart server read from our data directly (think of a query
to a geometryless table for example).

Opinions?
Cheers
Andrea
