Yes, and the fact that none of these piggyback payloads have ever come
to fruition, while we do continue to get the occasional ad-hoc small
satellite deployment opportunity, suggests that we need our own attitude
determination and control system if at all possible.

The most likely opportunity to piggyback a payload on a controlled
platform with its own power supply would be the ISS itself. Although
they've already got plenty of comm systems, one might pitch this as yet
another backup comm system. It wouldn't be terribly hard to network the
ground stations so that a conversation could be maintained as the ISS
moves from one to the next. To simplify the implementation, provide good
voice quality and a backup data capability, the system would have to be
completely digital.
