when you talk about a backtracking monad transformer which one are you 
refering to?  ralf hinze seems to have a whole bunch of papers on the 
matter, some of which seem to be a lot like the "Maybe" transformer and 
some seem very complicated (but presumable are very efficient).

i don't have access to the repository so i am not really doing anything 
at the moment.  i would be interested at looking at your transformres 
quite independently of the library...  are they available anywhere?  i 
think the main probelm with adding transformers to the library is that 
the amount of code grows quadratically in the number of transformers
(as one has to specify how each one interacts with every other one).
but of course if there is some ne wfunctionallity we should add it.
