I am not suggesting that clients modify anything. That would be very
racy. I am suggesting that clients have access to an API that reads
and parses this file under the hood (ie. the file is considered
internal private "API" to Zeitgeist, but dedicated libs are allowed to
access it).

I think we may wanna move in this direction too anyway if/when we
enable WAL on the main db which can allow clients direct read-only
access to the db (still through our APIs ofcourse, but avoiding the
dbus roundtrips).

Title:
  The datahub starts zeitgeist-daemon on startup

Status in Zeitgeist Client Library:
  New
Status in Zeitgeist Framework:
  New
Status in Zeitgeist Datahub:
  New

Bug description:
  We have been advising distros put zeitgeist-datahub into the autostart
  section for the sessions. This is better in theory because this way we
  only start a native daemon on login and can defer the launching of the
  heavier Python process zeitgeist-daemon.

  Unfortunately zeitgeist-datahub does DBus activation of the zeitgeist-
  daemon on startup so we really don't get the benefits we wanted.
  Bootcharts from Ubuntu 11.04 indicates that ZG eats about 1s on the
  login time and I don't think that is acceptable for ZG in the longer
  run. That is - no catastrophe for 11.04, but we should fix this.

  (a related issue seems to be that the dbus activated zeitgeist-daemon
  seems to launch another datahub instance that then immediately becomes
  a zombie... ? :-/)
