Yep. And, of course, you can do fun stuff like expose what kind of  
inputs/outputs you are willing to accept, and potentially have  
different server implementations. Actually....thinking about it a bit  
more, and you have a distributed grid of machine learning, with  
Drupal slurping in results and spitting them back out again. Fun!
