i frequently have broken file: links. this might reduce their occurrence.
i'd like to be able to do this:
file:.../**/myfile
which would use bash's globbing mechanism or an elisp equivalent.
also perhaps this:
file:.../**/*myfile*
if one file results, i would like it to open as normal. if more than
one file results, i would like all of them to open in a dired-virtual
buffer. i think dired-virtual is in core.
the first case would prevent broken links by allowing myfile to be
moved as long as it is under ....
the second case would allow you to select a bunch of files that have a
common substring. it would also prevent broken links by allowing
myfile to be renamed slightly [such as compressed or uncompressed].
i think broken links are likely a common problem for org users. maybe
this can help prevent it.
does this sound like a good idea as an optional feature?
if no, then what would be a good implementation of a glob: link?

This could be useful. Here is something close. It does not use
dired-virtual. I couldn't figure out how to generate the ls -lR like
listing for each file, but if you know how to do that it should be
straightforward to modify.
#+BEGIN_SRC emacs-lisp
(defun glob-follow (path)
(interactive)
(let ((files (directory-files-recursively "." path)))
(if (= 1 (length files))
(find-file (car files))
(pop-to-buffer (get-buffer-create "*org-glob*"))
(erase-buffer)
(org-mode)
(insert
(cl-loop for file in files concat
(format "[[./%s]]\n" (file-relative-name file ".")))))))
(org-link-set-parameters
"glob"
:follow 'glob-follow)
#+END_SRC
Here is an example usage:
[[glob:.org$]]
