you probably know this already, but one of the nice things about hide glue is that it doesn't show up in the finish if you don't clean it up perfectly the way PVA glues do. of course, you may have more limited access after glue up like Bradley said.

one idea -full disclosure, I've never tried this - would be to apply a layer of hide glue as a masking agent. since hide glue is reversible, and assuming you'll have good access to the masked area after you apply the oil finish, you should be able to remove that high glue with heat and moisture after you're finish is applied.
