In The Inner Light, at the end of the story, the probe that was communicating with Captain Picard (and showing him the way of life for a now dead civilization). The intent of the probe was to say to someone else, "We were here and this is what life was like for us. Don't forget us."
But the probe only reached out to one person and once it finished the program, it stopped communicating with Picard.
Was the experience Picard went through a one time thing? Is there anything (even in the Expanded Universe) to indicate that others could experience the same program, or was the probe only capable of sending the message and running the program once?
