Wouldn't it be possible to automatically send out queries for random
blocks of a file to ensure that the file is available. If such queries
stay mostly unanswered, the file could be removed from the search
results, since its currently not completly available. If all random
queries on the other site are answered, the probability for the
availability of the file would be relativly good.
