ArenaNet:Guild Wars 2 suggestions/Xunlai House Extention 1 - The Record Keeper

(Discussion)
What it does
 * The Middle Man keeps track of what item are sold for how much, when and where, from whom to whom (this particular info is kept secret to use only when a violation is breach, ie scam or suspiciously large sums of gold has change hands)the rest of the infos are retrievable by talking to The Middle Man. Information beside the above mention are, how much does item X cost - for player to know the current market price of items, how often does trade occurs for item Z - for player to know how rare/common item Z is and etc (others to be included as see fit by Arena Net)
 * The Middle Man also helps players trade items that require large amount of gold in transaction between 2 players. It is the only way two account can transfer more then X amount of gold within a period of 24 hours(note1), to prevent RMT.


 *  Why this is a good idea
 * Convenience
 * Cut down scamming activities
 * Making it easier for players who are not power trader to get involve in the in-game trading market.
 * Enabling large amount of cash transfers between 2 players.
 * Preventing RMT


 * Why it may not work out
 * Server strain

Footnote
 * I put down server strain, but if this is a good idea (depending) will Arena Net please make it work.
 * Please note I've change the title of this suggestion to The Middle Man instead of The Record Keeper. Because now it does more then keeping records.
 * Note1 explain, Either a cool off time for a next large sum transfer or The Middle Man will red flag the accounts involve in the large sums of gold transfer if and when more then one large sums of gold has been transfers within a period of 24 hours. So that if the players is actually spending gold legally they will not be stop from doing so.
