Hi Chad,
What output format are you requesting? If you request gif or jpeg, you will get poor or no transparency. If you use PNG (format=image/png) then you will get great transparency.

I am outputting a png and still getting white (thougth it was black
for some reason)...
Here is the output in UDig: http://www.alteviltech.com/temp/NHDPlus_Zone08.jpg
And here in World Wind: http://www.alteviltech.com/temp/NHDPlus_Zone08_WW.jpg
Here is what I use in my WW XML file:
<WMSAccessor>
<ServerGetMapUrl>http://localhost:8080/geoserver/wms</ServerGetMapUrl>
<ServiceName>WMS</ServiceName>
<Version>1.0.0</Version>
<ImageFormat>image/png</ImageFormat>
<WMSLayerName>NHDWaterbody</WMSLayerName>
<UseTransparency>true</UseTransparency>
<Opacity>170</Opacity>
<ServerLogoFilePath>add-ons\sdss\sdss\sdss.png</ServerLogoFilePath>

Since it is showing up in in UDig, I think that the problem lies with WW. Either WW is messing up the request and asking a different image format. Or it can't render the PNG.
I can give the request a try in a day or two and see what might be wrong. But try asking the WW guys if they have an idea.

Ok, we hacked and tweaked the XML a bit and got it to work. Here is
how the WW XML looks now:

Yep.. now for the "fun" part.. need to do some styling changes so that
they are all not 1 color.

You really notice in the Flowline screen shot. That should be better
defined instead of a giant green spider web.

Ah yes, styling. Guaranteed to always take up a lot of time =)
On that note, we are working on an SLD editor in Geoserver that should really shorten the development time in creating an SLD. There is a basic one there now, but keep an eye out for the more advanced one when it comes out.
