HTTP 1.1 provides for byte-ranges within an HTTP request, but not
within a URL. There are serious technical questions as to what
it means to link to a byte-range of a file, for MIME types other
than plain text. (An arbitrary byte-range section of,say, 
an HTML or PDF file is not a complete document, in general.)

I think there are servers like John Franks wn server than in effect
define special URLs that refer to byte ranges (for example
to reference one article in a mailbox) but they do this in a way
that treats the URL as an arbitrary token needing no special
processing by the client.

If you are doing server-specific hacks it might make more
sense to use the nntp: or http: schemes to serve up articles
since the news: scheme in effect assumes any news server is
as good as any other.
