| Those won't be named utilities;  they will be adapters, with
| "tool-centric" interfaces.  For code which currently spells the lookup::
| 
|   catalog = getToolByName(some_context, 'portal_catalog')
| 
| I prefer::
| 
|   catalog = ICatalog(some_context)
| 
| rather than::
| 
|   catalog = getUtility(IGenericTool, 'portal_catalog')
| 
| which will permit us to do component-style indirections based on the
| type of 'some_context'.

And then I think the component architecture supports named adapters
no? Maybe I'm just dreaming *wink*.
