In addition to previously mentioned issues with OPTIONS (non- 
cachability), I'm hesitant to go with anything that suggests two  
different paths to get at a service description. If we're going to  
suggest that the service description be available via GET (I'm hoping  
via conneg), then *also* going with OPTIONS seems like an uphill  
battle, trying to drag public use of OPTIONS along with our desire to  
get widespread service descriptions.
