Sure!  I am always happy to elaborate. 

So with POG, the act of giving is governed by the ability to spend a Single coin with Age + Minimum Amount + Maximum value.
This means that it is equally beneficial (but more efficient) to store all your coins in one controller wallet.  For one, we will see distinct nicknames (thats good for accurate reports), for two we may have a Christian Economy feature in the future that ties to the address, and three- splitting the wallet offers no real advantage due to individual pool entries as the split coins age at the same rate (IE two wallets tithing more frequently are not capable of tithing more frequently than one wallet).  The single wallet will tithe just as frequently as possible for the difficulty level.

So in environment A, a user with a 100K balance split into 10 banknotes is exactly equal to a user with two wallets and 50K balance on each split into 10 banknotes (across 2 nodes).  All 20 of these banknotes age at the same rate and offer the same pool share percentage.  So there is no advantage to splitting the wallets - but its more efficient to have one (you have one miner running, you have one nickname), etc. 

If you want more POW mining you can still just set up the other nodes for POW only (without POG).
