@artch Chronicle would still show total score (but perhaps periodically cached values in stead of real-time). The type-specific amounts could be shown when you select the deposit structure.
Sharing score with room owner/depositor does not fully prevent in-alliance boosting but it would at least be limited. The "boosted" player would only get half the score from everything he deposits in rooms owned by his alliance mates. This would also result in the small players getting score on the board if an aggressive neighbour forces them to give their score (like what smaykit and I have this season).
