Hmm...people have made so many kinds of fences, you should be able to
find one that doesn't look man-made. :-)
A couple ideas...twisted or round helix "rope" instead of chains, a
large number of small, closely spaced posts, interlocking cylinders that
don't touch the neighboring posts, but come close, electrical arcs
(which wouldn't have any problem with ice buildup!), glowing tubes...

I don't see any reason that won't work...but I'm not sure it's the best
approach. The results will probably look too much like liquid...an
isosurface should be fine.

Using a particle_system object directly for wind-blown powdery snow
would take a *lot* of particles (lots of memory), even if confined to a
small area...you might have better luck with a particle system written
that generates a blob pattern, then use that pattern to place a snow
texture layer. For this, you could use your own particle system written
in POV Script, or the accessor functions for the particle_system data.
