Hello there udig-devel members. I hope in joining this mailing list you will be 
able to help me with some of my uDig woes.
 
As you maybe aware, GeoServer contains some non-standard WMS and SLD extensions 
that allow you to pass in parameters that allow you to customize how a getMap 
request is rendered.  For example, you can add "&env=param:value" to the end of 
the string to retrieve a map with customised colours or filter limits.  I would 
like to use this functionality in my uDig application, and i have not found 
anywhere in the GUI to add the custom parameters.
 
I would also like to add these layers automataically when my users configure 
the the application so that they can customize how my WMS server renders the 
map. At this point, using a WMF instead with a local SLD is not an option.
 
I have determined that i should use ApplicationGIS.addLayersToMap() with an 
IGeoReference, but i am unable to get much further than that.  I believe the 
correct IGeoReference implementation i need is a WMSGeoReference but i cannot 
find where this class is located.
 
I am very stuck at this point and I appreciate if someone could steer me in the 
correct direction to achieve my goal!
 
Many thanks in advance
 
James
