I agree that the case you bring up is different from the issues that Tony 
has been discussing.  However, to your point, I think we do need to start 
registering tools.  As Tom has indicated, there is not any easy way to 
discover tools, like Aladin, that can interact with VO services.  If these 
were registered, then DataScope, for example, could search the registry 
and present the user with the available choices of visualizers.  

So one question then is, are there any specific bits of metadata we should
include in the description of the tools, requiring an extension schema?  
Bob has suggested we consult previous endevours at software registries, 
like the one he worked on as an AISRP project.  

cheers,
Ray
