Thank you for your help and suggestion. I never did quite get the hang of the billbaggins liquid drops thing figured out well enough to make it work for this but I was able to implement your suggestion with the transmapping. Because the shower's glass doesn't have a UVMap that's easy to use I had to do a few things to get it to work. First, I set the glass to completely transparent so it doesn't appear at all. Next, I added a hi-res square plane (from the primitives prop library). I used a paint program (GIMP to be exact) to create a 2048 X 2048 pixel resolution square blank image. I filled this with a dark gray color using the fillbucket tool. I duplicated this image so I could go back to the all dark gray image in case something went wrong. Next, I used the circular/elliptical selection tool and went almost corner to corner (about 100 pixels in from the top and side edge). From the SELECT menu, I clicked INVERT SELECTION, then clicked FEATHER SELECTION and adjusted the feather amount from the default of 5 to 180. I selected the color white from the color palette, selected the fill bucket tool again, and changed it's toolbox properties to FILL ENTIRE SELECTION then clicked in the image. This filled the outer edge of dark gray box with white but gave it an airbrushed gradient that faded inward to the gray. I duplicated this image (again to keep from messing up beyond recovery) and chose the paint tool, the round brush, and sized up the brush to 200. I selected black from the color palette and began to paint in stroked to try and simulate what one might create with one's hand if wiping it across a frosted glass pane. I saved this as a JPG and called it SHOWERGLASS_FIGURE_TRANS.JPG. I then chose the previously duplicated image (with the dark gray circle with white gradient airbrushed edges) and again used the circular shaped brush to write the words HELP ME! and saved that as SHOWERGLASS_FIGURE_TRANS.JPG. Inside Poser, I added a hi-res square plane to my scene and applied the first transmap to it's transparency node and set the transparency to 1. From the poser edit menu, I chose duplicate clothplane and moved the new square along the X axis. In the materials room, I browsed the image map node to change the JPG file to the second image I saved from GIMP. Then, I adjust the scale, rotation, and position of each square for the scene's requirement. So now I was able to render the scene I wanted to create. I'm attaching the file to this post so others can see the result and be able to benefit from the advice and technique given here.
