Probably a silly question about soap storage

[Joegags]

Gentlemen-
This is probably a question that does not need to be asked, since what I am asking about has been done since shaving began (give or take a few years) but I will anyway to see if it generates any conversation...

Up to this point I have been storing my soaps in these:

The Container Store > Lock Ups

They work great - I either grate a puck of hard soap or press in a lump of soft Italian soap - the screw top closes tight and they stack and lock together for easy storage. Anyone looking for a way to store soaps, I highly reccommend the 6 oz. size.

Anyway, I recently bought 2 occupational shave mugs from ebay to add to the two traditional shave mugs I already own (the ubiquitous "Old Spice" ship on the front type I inherited from my father). I think I may want to start collecting shave mugs and start storing my soaps in those - a one puck per mug type of thing. Allowing for the fact that storage space will be a possible problem, I have two questions:

-Will there be a noticeable loss of scent in the soaps over time, since they will be stored uncovered?
-Is this a bad idea for the Italian soft soaps? Will they dry out and loose performance (I know you add water
each time you use it, but who knows?) Can the tallow in the soap go rancid?

As I said, I know this is the classic way to store and use shaving soap, but like a lot of us, as my soap and cream collection grows, the time between use of any one soap also grows. Could longer amounts of time sitting around uncovered "damage" the soaps?

This turned out to be a much longer post then I anticipated - sorry for that - but thanks in advance for any and all replies!
