So I looked at the old patches and the code a bit. There are multiple
use-cases for this stuff.

- systemd-journal-remote with the default service/socket in passive mode
  that receives a journal
- systemd-journal-upload the sender to the use-case above
- systemd-journal-gatewayd basically allows browsing the journal via http.
- systemd-journal-remote in 'active' mode with a custom service & 'getter'
  to pull the data.

I guess the last one is you're use-case? I suppose this is a good start.
I'd like to see the others eventually. But that will also require some
certificate handling etc. so that's more work.
