   But there are user-interface applications (e.g. TV UI, EGP,
   etc.) on the client or within a local system which do need to be
   able to specify details such as tuner and channel number.  For
   example, a UI app that goes through all the autoscanned channels
   on the first tuner and then on the second one might need to
   display tv:69?tuner=first followed by tv:2?tuner=second.

A UI application that is going through local resources using an API
uses the API data structures to name the resource: these structures
need not be represented as UR*s at all.

For example, an API can return an array of channel objects.  The
array would be indexed by a small integer.

	...
   Structured namespaces for physical TV channels already exist
   (e.g. NTSC, PAL, ATSC, etc.); so there is a sound basis on
   which to build a structured, uniform naming scheme (certainly
   more uniform that file:!).  Please let me know your thoughts.

Well, that's the point behind btv: it provides such a uniform,
transport-independant scheme.
