Should not need any pixelshaders. Fixed-function. I cannot test this on anything other than my ATI 9200 tho and I do not know what the minimum requirements might be.

I updated the website with the code to do 3 textures as well as some changes to the effect file, better comments, and a little instructions.

Theres a screen with 4 textures and an EBM water effect start.

I want to get this thing tested out good, then posted on the wiki.
