I really don't like this rule overall in Dark Heresy, although I understand why it's in the game. It's an extension of the same rules used in Rogue Trader.
First off, while I realize that it may take 20-30 years of real time, to catch on in the vein of AD&D (if in fact it ever does to that extent), it still seems to be a form of communism, and since I live in a country that promotes capitalism I feel that this 'closet' form of promoting communism is in bad taste at the least, and possibly treasonable at the worst.
Further, for game purposes, I have a character that has, over a period of time in the campaign that she ran in, developed an increasing level of piousness. After ascending, strict interpretation of this rule means that the character would no longer be able to pay her tithe to the church. Worse, in her eyes, it allows the Inquisitor of her group to have full control over how much income the group then makes or has... which seems to place the Inquisitor on a pedestal above the Emperor.
However, with all that said, if you use a payroll system, then one would have to spend large amounts of time trying to put a value on every piece of equipment in the game that has not been tagged with a price.
This rule is a modification of those rules that I use in my campaign.
Basically all it is is you reduce the amount of Influence for Acquistion by a percentage, and then give that same percentage to the players as per 'Pocket Money & Monthly Incomes'.
For my game I reduce the player's Inquisitor Influence by 20%. This reduction is counted off for making rolls...but the actual percentage is used in case of a failed roll.
For example, in my game the player's Inquisitor has a base of 60 Influence. A reduction of of 20% lowers this number to 48 for the purpose of actually acquiring items. But if a roll is made that misses up to 60 (the actual base amount) would not cause Influence to fall for 'Decrease due to failure'.
For the player's pocket money, this then works out to them receiving 200 thrones per rank level, per month.
I would like input on this one... although I do not anticipate changing my view on it, I want to see if others out there might have had similar thoughts, and didn't know how to share them... or might have been afraid to?
