I am a little less clear than Matt is here.  Since Kepler doesn't have 
native support for Web Services, they must be "sucked" into Kepler, 
e.g., through Ilkay's Web Service actor.  These services can then be 
further parameterized and saved via MoML.  And, ultimately, semantically 
annotated (we are focusing our semantic annotation on ptolemy not on web 
services in general).   Thus, *any* web service can be configured and 
stored in MoML as well as *any* "local" actors/parameters/directors, 
etc.  That seems more general, doesn't it?
