/* here we are running a background process that calculates the reputation scores
 * for each of the IDs....
 * 
 * As this class will be extensively used by many other threads... it is best
 * that we don't block at all. This should be in a background thread.
 * Perhaps a generic method to handle this will be advisable.... but we do that later.
 *
 * To start with we will work from the Posted service.
 *
 * 
 *
 * So Reputation....
 *   Three components:
 *     1) Your Opinion: Should override everything else.
 *     2) Implicit Factors: Know the associated GPG Key.
 *     3) Your Friends Opinions: 
 *     4) Your Friends Calculated Reputation Scores.
 *
 * Must make sure that there is no Feedback loop in the Reputation calculation.
 *
 * So: Our Score + Friends Scores => Local Reputation.
 *  Local Reputation + Friends Reputations => Final Reputation?
 *
 * Do we need to 'ignore' Non-scores?
 *   ---> This becomes like the "Best Comment" algorithm from Reddit...
 *   Use a statistical mechanism to work out a lower bound on Reputation.
 *
 * But what if your opinion is wrong?.... well likely your friends will
 * get their messages and reply... you'll see the missing message - request it - check reputation etc.
 *
 * So we are going to have three different scores (Own, Peers, (the neighbour) Hood)...
 *
 * So next question, when do we need to incrementally calculate the score?
 *  .... how often do we need to recalculate everything -> this could lead to a flux of messages. 
 *
 *
 * 
 * MORE NOTES:
 *
 *   The Opinion Messages will have to be signed by PGP or SSL Keys, to guarantee that we don't 
 * multiple votes per person... As the message system doesn't handle uniqueness in this respect, 
 * we might have to do FULL_CALC for everything - This bit TODO.
 *
 * This will make IdService quite different to the other GXS services.
