   2) How can I make a buffer's display different than the buffer itself?

You might try to use a find-file-hook that extracts the data from the
file, inserts it in the desired format at the beginning of the buffer,
and either erases the rest of the buffer or hides it by narrowing. A
corresponding write-file-hook would reverse the process. Check out
tar-mode by Jamie Zawinski (jwz@lucid.com), posted to the net not long
ago; it uses narrowing.

Whether to use narrowing or erasure depends on how much of your data
that is to be hidden from the user, and how hard it is to recreate
that data. For example, if the hidden data is only intra-file cross
references, it might be better to recompute those in the
write-file-hook; if it's contents of hidden text fields, you cannot
erase it. 

If you use narrowing, you will of course have to disable 'widen.
