I can assure you the top temperature is not a problem!

We rarely see above 30oC (around 86oF.) On the odd days we will see a max of say, 37oC (which equates to 98.7oF).
The problem may be the fluctuations on a day to day basis. While I profess to have never measured the difference in temperature in the basement, I know the rest of the house can get some wildly fluctuating temperatures between the high heat of day and the lows at night.
The humidity is also quite low. I am going to buy a small portable humidistat and stick it in the basement to get a gauge on how "off" it is. If I had to guess, with the added humidity that we introduce through our humidifier tied into the furnace, I would say 20% relative humidity. We're talking some potentially dry corks here I would guess.

To answer this question, at present I simply have some storage under the stairs but am planning out the basement, to be built out over the next few years, with a dedicated room that will be walled off (I was thinking with brick with a layer of thick R24 or higher insulation outside of that, with sheetrock/drywall over wood studs on the outside of the wall) to mimic the concrete walls that will make up the 'other side' of the walls for the cellar room. Inside will be racks and that is about it. Nothing fancy. On the outside, the "study'/rec room will have book cases with display cases built in for various old bottles that have been emptied and are meaningful, cork display, tongs, etc. A small wet bar with a small gas burner (for heating the port tongs) in the corner of the room will complete the setup and allow for the decanting/pouring of the good stuff after tongs have removed the bottle tops.
The humidity has me a bit worried, but the day-night fluctuations in temperature could be scary as well. Will have to take some calculations over the next few months as it starts to get warm and determine if this is something to be concerned about or whether it is all, as Derek suggested at the beginning of the thread, a bit too anal... :?
