  org.altlinux.alterator sender on the remote machine are retransmitted to the
  local d-bus. The signal's object path and signal name fields are replaced. In
  the object path, two more sections are added before the last one. The first
  is the word 'connection'. The second is the connection name. The executor
  module appends a unique bus name to the signal name, replacing periods and
  colons with underscores. When retransmitting, the unique bus name is replaced
  with the connection name, separated by an underscore.
