Just some random thoughts. In jarchive, I believe you have two options:

- Use tramp-archive. This is restricted to local GNU/Linux systems(*),
  but it shall work out of the box. If you have a local jar archive,
  just map the file name to something like

  jar:file:///home/albinus/.m2/repository/org/clojure/clojure/1.10.3/clojure-1.10.3.jar!/clojure/core.clj
  => /home/albinus/.m2/repository/org/clojure/clojure/1.10.3/clojure-1.10.3.jar/clojure/core.clj

  Try it out, it will work out of the box :-)

  If the jar archive is located on a remote host, say /ssh:user <at> host:,
  just prepend that remote file name location:

  /ssh:user <at> host:/home/albinus/.m2/repository/org/clojure/clojure/1.10.3/clojure-1.10.3.jar/clojure/core.clj

  Try it out, it will work out of the box :-)

- Use jarchive as it is, but on a local cop< if it is located on a
  remote host. If the jarchive is located on, /ssh:user <at> host:, copy it
  locally:

  (copy-file "/ssh:user <at> host:/home/albinus/.m2/repository/org/clojure/clojure/1.10.3/clojure-1.10.3.jar"
            "/tmp/home_albinus_.m2_repository_org_clojure_clojure_1.10.3_clojure-1.10.3.jar"

  Let your jarchive file name handler run on this temp file /tmp/home_albinus_.m2_repository_org_clojure_clojure_1.10.3_clojure-1.10.3.jar!/clojure/core.clj

(*): There are plans to integrate libarchive(3) natively into Emacs. Then
     this would work on all systems.

Best regards, Michael.
