To solve this I think Blizzard should, at some point in the future, consider allowing enchanters to apply the enchantment to a "scroll" of some sort that is a one-time use only item.  This allows the enchanter to put his enchant on the auction house to be bid on by everyone just like every other item in the game.  The idea is that it allows enchanters to enchant at their leisure, put the "scroll" (or whatever item) with the enchantment applied on the auction house, a buyer buys the scroll and enchants the appropriate item at their leisure, the "scroll" disappears from inventory.  This will help many people in many different ways.  One thing comes to mind: Much less spam on trade and general channels as we won't have to listen to enchanters all day and night sounding like carnival barkers trying to sell stuff you may or may not want or care to hear about.

Just my two cents.
