> There is a use case I encounter in which a random forest model is passed to remote server over a REST API and is used for scoring the incoming requests in there. 
> In such a scenario it is highly inefficient to write the byte buffer received at the remote server on the filesystem and then use Mahout APIs to load the forest.  
> We should be able to load the forest from the byte buffer received. This is useful in non-map-reduce usecases of classification like that mentioned above.
