Hy Chris,
If you can understand french, I found a tutorial on a blog about this
question, some weeks ago. As Edward wrote it, you cna do it with
buffers, and then display it wih different opacities.
Here is the article : http://simonmercier.net/blog/?p=1214
He creates buffers that do not overlap ("ring" buffers) on the server
side, and then applie transparency and color with MapServer.

Thank you, Edward.
I wouldn't want to end up with the polygon being smaller, so would
that approach still work if a positive value was used?

Chris,
My approach would be to use the geometric transformation "buffer"
several times on the polygon. Using a negative value, you would get
polygons smaller than the input area. with every transformation you
set a different colour to achieve a fading line effect, though
generated using polygons.
Kind regards,
Edward

Subject: [Geoserver-users] Polygons with outlines using gradients
Hello all,
Is it possible to style polygons so that their outline appears as a
gradient? I'd like to define a coastline, for example, using a line
that is, say 5 pixels wide, but whose colour fades to transparent. The
gradient should be oriented with the solid colour closest to the
inside of the polygon and the lighter colour furthest away from the
polygon.
Not the best explanation, but hopefully you will understand what I mean!
Thanks
Chris
