G.M.Doolittle raised queen cells above an excluder in a queenright colony. Ben Harden, an Irish beekeeper, does the same and says it works because the queen spreads a pheremone from the "Amhart gland" in her feet. Since she can't walk above the excluder, the pheremone is weak or non-existant in the cell-building chamber. Read about it here:

I don't know how it works but I have had success raising queens in this way.
