There is a wordProb function for FLMs, since FLMs are just a special 
kind of LM class.
You need create an LM object of class ProductNgram and then invoke the 
wordProb function in it.
Look in lm/src/ngram.cc for an example (look in the places where the 
variable "factored" is used).

There were problems with the mailing list admin software.  We solved 
those and there is now an easy way to join/leave the list.  Just go to 
http://www.speech.sri.com/mailman/listinfo/srilm-user/ and follow the 
instructions there.
