+Experiments
+-----------
+The approaches experimented-with so far (later versions do not _necessarily_
+obsolete earlier ones, they're just different):
+
+| Name | Status | Language | Tested-on | Description |
+|--------|---------------------|-----------|-------------------------|-------------|
+| __x1__ | Archive, complete | Bash, AWK | Ubuntu 16.04 | Single, synchronous script, saving state in text files |
+| __x2__ | Legacy , complete | Bash, AWK | Debian 10, Ubuntu 18.04 | Parallel processes: collectors, cache and reporters; passing messages through a single named pipe |
+| __x3__ | Archive, incomplete | OCaml | Debian 10 | Re-write and refinement of __x2__ |
+| __x4__ | Archive, incomplete | Dash, AWK | Debian 10 | Sensors are completely decoupled daemons, cache is a file tree |
+| __x5__ | Current, incomplete | C | Ubuntu 18.04 | Sensors are completely decoupled daemons, writing to dedicated named pipes, bar repeatedly `select`s and reads the pipes. |
