Until recently (well, some months ago...), BMRT didn't have support
for displacement mapping, so don't worry.  I think that what you're
currently doing is a very interesting experiment, and that the goal
isn't to become totally RM compatible.  Being able to use custom
texture algorithms will be a significant leap, and will quickly bring 
very useful things, as textures' self-antialiasing, for example...
