I have already asked for this one times ago.
In France, for example, you have a huge number of Danger Areas or Restricted Areas that need a prior radio contact with the Military zone manager (using a specific frequency, of course) if you want to transit.
IMHO, the best way to implement it is to add a "comment" field to the waypoint dialog. The comment should be displayed when hitting the waypoint and printed in the PLOG (and saved with the flightplan of course).
