I don't understand what you meant by the last sentence.  Currently,
make-temp-name doesn't support remote files and doesn't pay attention
to temporary-file-directory.

It seems to me that we need to extend make-temp-file to support remote
files, but I see no reason to extend temporary-file-directory for that
purpose, sincea remote version of make-temp-file will invoke utilities
that might have their own ideas about where temporary file should live
and how they should be called.
