That would all be wonderful and very useful. Thank you!!
BTW, I believe there are two kinds of OSMIC references:
references to versions, which return the string of pointers that
comprise that version, and pointer dereferences which return
actual content from the primedia stream.

Close; take a look at my "text transcopyright" RFC draft. The idea
is to specify a new fragment identifier that can be applied
to existing URIs so that you can use "file:" for local files,
plus "http:" and all other existing protocols. Something like
"|byte[2-49,57-68],char(SJIS)[101-197]" for bytes 2-49 and 57-68,
plus Shift-JIS (a variable byte length encoding) characters 101-197.
Other kinds of selection (by line, by string match, etc.) should
also be supported. I believe the HyTime standard already describes
a very general set of selectors that support things including multiple
dimensions (for images, 3D objects or videos) and user-defined dimensions.
Unfortunately XML has apparently only adopted the hierarchy selection
parts of this standard, not surprisingly since XML can basically only
handle documents that can be described as a hierarchy. :-(

It's a CGI script that preprocesses a <TXT SRC> tag in HTML documents
and returns a normal HTML document with the result of evaluating all
the <TXT SRC> tags, and with all the HREFs changed to point back through
the script so that further documents retrieved will also be preprocessed.
Other ways to do this include with a web proxy (which would support
users of that proxy server) or with a web server module (which would
support the feature for pages hosted on that server).

It's a hypermedia linkbase partly inspired by Xanadu; see www.multicosm.com.
