What changes should be made to the DGM calculation in the presence of miners that are mining at different difficulty levels? For example, a pool that dynamically adjusts difficulty based on the users hashrate, or one that allows the user to select their own target value?

It's more or less the same, but instead of p=1/D you should use throughout p=d/D, where d is the difficulty of the current share submitted.

Pardon my ignorance to this issue but I was looking over your initial post and I was trying to understand why with a variable share difficulty that p would turn into d/D? Wouldn't it be 1/d? I guess I don't understand where D comes into play with variable share difficulty.

p is the probability that a share will be a block. If the global difficulty is D and the share difficulty is the standard 1 then p=1/D. If the share difficulty is d then p=d/D.

Ah, so it should have always been d/D? Where d was always 1 until now?

Exactly.
